Question

If the breadth of a rectangle is one-third of its length and perimeter is 32 ft, find the length and breadth of the rectangle. square​

Answer 1

breadth = 4 ft ; length = 12 ft

Explanation:

p/2 = 32/2 = 16ft

l + b = 16

b = 1/3 l

l + 1/3 l = 16

(3 + 1)/3 l = 16

4/3 l = 16

l = 16 · 3/4

l = 4 · 3

l = 12 ft

b = 12 · 1/3

b = 4 ft
