Question

The perimeter of a rectangle is 36cm.If it is length is 10 cm find its breadth​

Answer 1

Question:-

The perimeter of a rectangle is 36 cm. If its length is 10 cm, find its breadth.

Answer:-

Given:-

`\bullet` Perimeter (P) of a rectangle is 36 cm.

`\bullet` Length (L) of a rectangle is 10 cm.

To Find:-

Breadth (B) of a rectangle.

Solution:-

We know,

P = 2(L + B)

So,

36 = 2(10 + B)

36 = 20 + 2B

36 - 20 = 2B

16 = 2B

B = 16/2 = 8 cm.

Breadth (B) of a rectangle is 8 cm. [Answer]

Answer 2

The perimeter of a rectangle is 36 cm, its breadth is 8 cm

Explanation:

For a given rectangle

Perimeter (P) = 36 cm

length (L) = 10 cm

Now,

Perimeter (P) = 2 × (length + breadth)

P = 2 × (l + b)

36 = 2 × (10 + b)

36 = 20 + 2b

2b = 36 - 20

2b = 16

b = 16 ÷ 2

b = 8 cm

Thus, The perimeter of a rectangle is 36 cm, its breadth is 8 cm
