Perimeter of a Rectangle

2Save

Perimeter of the rectangle = PQ + QR + RS + SP

= b +l + b + l

= 2b +2l

Again,

ABCD is a rectangle. We know that the opposite sides of a rectangle are equal.

Perimeter of a Rectangle

AB = CD = 5 cm and BC = AD = 3 cm

So, the perimeter of the rectangle ABCD = AB + BC + CD + AD = 5 cm + 3 cm + 5 cm + 3 cm = 16 cm

It can be written as 5 cm + 5 cm + 3 cm + 3 cm

= (2 × 5) cm + (2 × 3) cm

= 2 (5 + 3) cm

= 2 × 8 cm

= 16 cm

We ADD length and breadth twice to find the perimeter of a rectangle.

Perimeter of a rectangle = 2 (length + breadth)

Let us consider some of the examples on perimeter of a rectangle:

1. The length of a rectangle is 4 cm and its breadth is 2 cm. Find its perimeter.

Solution:

Length = 4 cm

Breadth = 2 cm

Examples on Perimeter of a Rectangle

Therefore, perimeter of the rectangle

= 2 (length + breadth)

= 2 (4 + 2) cm

= 2 × 6 cm

= 12 cm

2. A rectangular SWIMMING pool is 9 m long and 4 m broad. Find the area of the swimming pool.

Solution:

Length of the rectangular swimming pool = 9 m

Breadth of the rectangular swimming pool = 4 m

Therefore, perimeter of the rectangle swimming pool

= 2 (length + breadth)

= 2 (9 + 4) m

= 2 (13) m

= 2 × 13 m

= 26 m

3. The length of a rectangle is 4.5 m and the breadth is 1.5 m. Find the perimeter.

Solution:

Length = 4.5 m

Breadth = 1.5 m

Perimeter of a Rectangle Problems

2Save

Perimeter = 2(length + breadth)

= 2 × (4.5 m + 1.5 m)

= 2 × 6 m

= 12 m

Therefore, the perimeter is 12 m.

4. A rectangle display board is measuring 8 m by 6 m. Robert wants to add a ribbon border around the display board. What is the length of ribbon that he will need? If the cost of the ribbon is $ 15 per metre then how much money does Robert needs to buy the ribbon?

Solution:

Length of the display board = 8 m

Breadth of the display board = 6 m

Perimeter of the display board = 2(Length + Breadth)

= 2(8 + 6) m

= 2 × 14 m

= 28 m.

Cost of ribbon is $15 per metre.

Therefore, total cost for 28 m long ribbon = $15 × 28

= $420.

ong>Answer:

The third proportion is DEFINED as a:B::b:C.

Here we have 15:45::45:c, or

c = 45*45/15 = 135.

So the third proportion is 15:45:;45:135.

ong>Step-by-step explanation:

Let

x

equal one NUMBER and

y

the other number.

One equation would be the sum of the numbers.

x

+

y

=

12

the other equation would be the difference of the two numbers

x

−

y

=

4

Now add the two equations

x

+

y

=

12

and

x

−

y

=

4

(adding

+

y

and

−

y

=

0

)

so

2

x

=

16

Now divide both sides by 2

2

x

2

=

16

2

This gives

x

=

8

Now substitute x into one of the equations and SOLVE for y

8

+

y

=

12

subtract 8 from both sides

8

−

8

+

y

=

12

−

8

This gives

y

=

4

PUT VALUES into the SECOND equation to check

8

−

4

=

4

=

check

x

=

8

and

y

=

a = (-8)

b = (-7)

1.) a - b

=> (-8) - (-7)

=> (-8) + 7

=> (-1)

2.) b - a

=> (-7) - (-8)

=> (-7) + 8

=> 1

Now,

➙ (-1) ≠ 1

=> a - b ≠ b - a

ong>Answer:

19 sahi 7/47 day

Step-by-step explanation:

Total work will the LCM of all that days...

LCM of 15,20 and 25 is 300

now let the total work is 300 then

A ka ek din ka kaam = (Total work)/(day) = 300/15 = 20

like that,

B ka ek din ka kaam = 300/20= 15

C ka ek din ka kaam = 300/25 =12

Ab A ek dim kaam krega uske BAAD B ek din Kaam karega fir C ek din kaam karega aur aise HI kram chalta rahega to..

A ka ek din ka kaam + B ka ek din ka kaam + C ka ek din ka kaam = 3 din ka kaam = 20+15+12 = 47

teeno ke teen din ke kaam ka ausat = (20+15+12)/3 = 47/3

ab poora din = 300÷ (47/3) =300*3/47

900/47 = 19 sahi 7/47 day

ong>Answer:

ESKA answer UPPER PAPER me hai.

ong>Step-by-step explanation:

Prime FACTORIZATION of a number: finding the prime numbers that multiply TOGETHER to make that number.

96 = 25 × 3;

96 is not a prime, is a composite number;

120 = 23 × 3 × 5;

120 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

conclusion is

, hcf,

(96; 120) = 24 = 2^3 × 3: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.
