Question

The length of a rectangle is 15 cm more than its width.if the perimeter is 150 cm, find the dimensions (length and breadth) of the rectangle.

Answer 1

Answer:

length is 45 cm

breadth is 30 cm

Step-by-step explanation:

l is 15+x

b is x

perimeter is 2(l + b) = 150

perimeter is 2(15+x+x) = 150

30+4x = 150

4x = 120

x = 120/4

x is 30

b =x = 30 cm

l = x+15 = 30+15 = 45 cm
