Perimeter ofrectangle = 2(length + breadth ) 56 = 2 ( 2x-800. + x ) 56 /2 = 2x -800+ x 28 = 2x+x - 800 28 = 3x - 800 28 + 800 = 3x 828 = 3x therefore , x = 828 /3 = 276 so.

22755.

length of a rectangle is 8 meter less then twice its breath if the perimeter of the rectangle is 56cm find the lenght and breath

Answer»

ANSWER:

convert 8m into cm

8×100 = 800cm

LET's consider

Breadth of rectangle = x

length of rectangle = 2x-800

Perimeter of rectangle = 56

To find : length and breadth

so...

Let's solve.

Perimeter ofrectangle = 2(length + breadth )

56 = 2 ( 2x-800. + x )

56 /2 = 2x -800+ x

28 = 2x+x - 800

28 = 3x - 800

28 + 800 = 3x

828 = 3x

therefore ,

x = 828 /3

= 276

so. Breadth is 276 cm

LENGHT = 2x - 800

2(276)-800

552 -800

-248 cm

so, Length is -248 cm

Breadth is 276 cm

Hope it's helpful

Thankyou

Answer» Answer: Let speed of TRAIN B = x 120/x= √(9/16) => x = 4 x 120/3 = 160 km/hr Note : This can be solved without using this formula by using fundamentals of Time, Speed & Distance. Step-by-step explanation: Derivation of formula : Let x be the total distance and t be the time at which the two trains meet. Let S1, S2 are speeds of train A, train B respectively and a & b are the times at which they reach the destination after they meet. x = t(s1 + s2) ...(1) x = (t + a)s1 ...(2) x = (t + b)s2 ...(3) Solving (1), (2) & (3) t = √(a*b) => Time to meet is the Geometric Mean of individual time after meeting. => s1/s2 = √(b/a)

Answer»

Answer:

Let speed of TRAIN B = x

120/x= √(9/16)

=> x = 4 x 120/3 = 160 km/hr

Note : This can be solved without using this formula by using fundamentals of Time, Speed & Distance.

Step-by-step explanation:

Derivation of formula :

Let x be the total distance and t be the time at which the two trains meet.

Let S1, S2 are speeds of train A, train B respectively and a & b are the times at which they reach the destination after they meet.

x = t(s1 + s2) ...(1)

x = (t + a)s1 ...(2)

x = (t + b)s2 ...(3)

Solving (1), (2) & (3)

t = √(a*b)

=> Time to meet is the Geometric Mean of individual time after meeting.

=> s1/s2 = √(b/a)

Answer» ★ How to do :- Here, we are GIVEN with some of the rational numbers that should be solved separately. On the other side, we are given with other three rational numbers in which they should be solved separately. The FIRST PART can be considered as LHS and the second part can be considered as RHS. We can solve both of them separately and then, we can compare the results of both pairs. This concept can do be known as associative property in which on LHS, we group first two numbers and on LHS, we group the last two numbers and vise versa. So, let's solve!! $\:$ ➤ Solution :- ${\tt \leadsto \bigg( \dfrac{3}{7} + \dfrac{7}{9} \bigg) - \dfrac{2}{7} \neq \dfrac{3}{7} - \bigg( \dfrac{(-7)}{9} - \dfrac{2}{7} \bigg)}$ LHS :- ${\tt \leadsto \bigg( \dfrac{3}{7} + \dfrac{7}{9} \bigg) - \dfrac{2}{7}}$ First solve the numbers in bracket.

Answer»

★ How to do :-

Here, we are GIVEN with some of the rational numbers that should be solved separately. On the other side, we are given with other three rational numbers in which they should be solved separately. The FIRST PART can be considered as LHS and the second part can be considered as RHS. We can solve both of them separately and then, we can compare the results of both pairs. This concept can do be known as associative property in which on LHS, we group first two numbers and on LHS, we group the last two numbers and vise versa. So, let's solve!!

$\:$

➤ Solution :-

${\tt \leadsto \bigg( \dfrac{3}{7} + \dfrac{7}{9} \bigg) - \dfrac{2}{7} \neq \dfrac{3}{7} - \bigg( \dfrac{(-7)}{9} - \dfrac{2}{7} \bigg)}$

LHS :-

${\tt \leadsto \bigg( \dfrac{3}{7} + \dfrac{7}{9} \bigg) - \dfrac{2}{7}}$

First solve the numbers in bracket.

LCM of 7 and 9 is 63.

${\tt \leadsto \bigg( \dfrac{3 \times 9}{7 \times 9} + \dfrac{7 \times 7}{9 \times 7} \bigg) - \dfrac{2}{7}}$

Multiply the numerators and denominators of both fractions.

${\tt \leadsto \bigg( \dfrac{27}{<klux>63</klux>} + \dfrac{49}{63} \bigg) - \dfrac{2}{7}}$

Write both numerators with a common denominator.

${\tt \leadsto \bigg( \dfrac{27 + 49}{63} \bigg) - \dfrac{2}{7}}$

Add them now.

${\tt \leadsto \dfrac{76}{63} - \dfrac{2}{7}}$

LCM of 63 and 7 is 63.

${\tt \leadsto \dfrac{76}{63} - \dfrac{2 \times 9}{7 \times 9}}$

Multiply the numerator and denominator of second fraction.

${\tt \leadsto \dfrac{76}{63} - \dfrac{18}{63}}$

Subtract the fractions now.

${\tt \leadsto \dfrac{76 - 18}{63} = \dfrac{58}{63}}$

$\:$

RHS :-

${\tt \leadsto \dfrac{3}{7} - \bigg( \dfrac{(-7)}{9} - \dfrac{2}{7} \bigg)}$

First solve the numbers in bracket.

LCM of 9 and 7 is 63.

${\tt \leadsto \dfrac{3}{7} - \bigg( \dfrac{(-7) \times 7}{9 \times 7} - \dfrac{2 \times 9}{7 \times 9} \bigg)}$

Multiply the numerators and denominators of both fractions.

${\tt \leadsto \dfrac{3}{7} - \bigg( \dfrac{(-49)}{63} - \dfrac{18}{63} \bigg)}$

Write both numerators with a common denominator.

${\tt \leadsto \dfrac{3}{7} - \bigg( \dfrac{(-49) - 18}{63} \bigg)}$

Subtract them now.

${\tt \leadsto \dfrac{3}{7} - \dfrac{(-67)}{63}}$

LCM of 7 and 63 is 63.

${\tt \leadsto \dfrac{3 \times 9}{7 \times 9} - \dfrac{(-67)}{63}}$

Multiply the numerators and denominators of first fraction.

${\tt \leadsto \dfrac{27}{63} - \dfrac{(-67)}{63}}$

Write the second NEVER in numerator with one sign.

${\tt \leadsto \dfrac{27 - (-67)}{63} = \dfrac{27 + 67}{63}}$

Add the numerators now.

${\tt \leadsto \dfrac{94}{63}}$

$\:$

Now, let's compare the results of LHS and RHS.

${\tt \leadsto \dfrac{58}{63} \: \: and \: \: \dfrac{94}{63}}$

We can see that they are like fractions, by which we can compare them easily.

${\tt \leadsto \dfrac{58}{63} \neq \dfrac{94}{63}}$

So,

${\sf \leadsto LHS \neq RHS}$

$\:$

${\red{\underline{\boxed{\bf So, \: they \: aren't \: equal}}}}$
