Answer»

Answer:

36cm ,33cm

Step-by-step explanation:

let length of rectangle = X

breadth of rectangle = x-3

A.T.Q.

(x)(x-3) = (x+9)(x-3-5)

The length and breadth of a rectangle are 757 and 60 CM respectively find its area

Answer»

ANSWER:

AREA of rectangle is 45,420cm²

\ $\rule{250}{2}$

EXPLANATION:

Here in this question concept of area of rectangle is used. We have given SIDES of rectangle be 757cm and 60cm. We have to find area of the given rectangle.

$\rule{250}{2}$

To find the area of rectangle, we can apply the following formula to find area of rectangle:

★ Area of rectangle=Length×Breadth

$\rule{250}{2}$

GIVEN:

Length=757cm

Breadth=60cm

$\rule{250}{2}$

TO FIND:

Area of rectangle

$\rule{250}{2}$

SOLUTION:

★ Area of rectangle=Length×Breadth

Area of rectangle=757cm×60cm

Area of rectangle=45,420cm².

So the required area of rectangle is 45,420cm².

$\rule{250}{2}$

ADDITIONAL INFORMATION:

More important formulae:-

★ Perimeter of rectangle=2(L+B)

★ Perimeter of square=4×Side

★ Area of square=Side²

★ Perimeter of rhombus=4×Side

★ Area of right ANGLED triangle=½×Base×Height

31.	Please answer me nowques: if the mean of the folloeing data is 20.2. Find the value of P
Answer» According to the question, <P> MEAN = 20.2 So, ∑fixi/∑fi = 20.2 So we get , ∑fixi = (10×6) + (15×8)+(20×p)+(25×10)+(30×6) =610+20p we also get , ∑fi=6+8+p+10+6 =30+p Therefore , ∑fixi/∑fi=20.2 (610+20p) / 30(p=20.2 20.2 (30+p) / 30 p = 20.2 606 + 20.2 p = 610+20p 20.2p - 20 p = 610 - 606 0.2p =4 p = 4/0.2 p =20

31.

Please answer me nowques: if the mean of the folloeing data is 20.2. Find the value of P

Answer»

According to the question,

<P>

MEAN = 20.2

So,

∑fixi/∑fi = 20.2

So we get ,

∑fixi = (10×6) + (15×8)+(20×p)+(25×10)+(30×6)

=610+20p

we also get ,

∑fi=6+8+p+10+6 =30+p

Therefore ,

∑fixi/∑fi=20.2

(610+20p) / 30(p=20.2

20.2 (30+p) / 30 p = 20.2

606 + 20.2 p = 610+20p

20.2p - 20 p = 610 - 606

0.2p =4

p = 4/0.2

p =20

35.	Express 16 ^24 in exponential form with base 2

35.

Express 16 ^24 in exponential form with base 2

Answer»

SOLUTION:-

We have to write 16²⁴ in EXPONENTIAL FORM with base 2

16 can be written as

16 = 2 × 8

16 = 2 × 4 × 2

16 = 2 × 2 ×2 ×2

16 = 2⁴

So,

16²⁴ = (2⁴)²⁴

It is in form of

$(a {}^{m} ) {}^{n} \: = a {}^{mn}$

So,

$(16 {}^{4} ) {}^{24} = 2 {}^{4 \times 24}$

$(16 {}^{4} ) {}^{24} = 2 {}^{<klux>96</klux>}$

Now its base is 2

So,

a

Exponential form of 2⁹⁶ = 2 × 2 × 2 ×2 ×2 ×2 ...× 2 ...96 times
