Question

The breadth of the rectangle is 4 times its length. If the perimeter of the rectangle is 100 cm. Find its length and breadth.

Answer 1

Answer: Length of rectangle = x

Breadth of rectangle= 4x

Perimetre of rectangle= 100cm

P= 2(L+B)

100= 2(x+4x)

5x= 100/2

5x= 50

x= 50/5

x=10

Therefore, L= 10cm

B= 4*10

= 40cm
