Question

Length of a rectangle is three times its breadth. Perimeter of the rectangle is 40 cm. Find its length and width.

Answer 1

Answer:

The length is 15 and the width is 5

Step-by-step explanation:

Let the breadth  be x cm then its length be 3x.

Perimeter of the rectangle = 2 (x+3x)

40=2(x+3x)

40=8x

x=5

breadth = 5

length = (5×3) = 15
