Question

The perimeter of a rectangle is 72 cm. If its is 17 cm, what is its breadth?​

Answer 1

Given :-

• Perimeter = 72 cm
• Length = 17 cm

To Find :-

Breadth

Solution :-

We know that

Perimeter of rectangle = 2(l + b)

⇒ 72 = 2(17 + b)

⇒ 72/2 = 17 + b

⇒ 36 = 17 + b

⇒ 36 - 17 = b

⇒ 19 = b

∴ Breadth of rectangle is 19 cm

Answer 2

Answer:

b = P/2 - L

b = 72/2 - 17

b = 36 - 17

b = 19 ans
