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

Answer:-## Given:-

Perimeter (P) of a rectangle is 36 cm.

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

8cm. [Answer]Answer:The perimeter of a rectangle is 36 cm, its breadth is 8 cm

Step-by-step 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=8cmThus,8cm-TheUnknownScientist
