Question

A rectangle’s perimeter and its area have the same numerical value. The length of the rectangle is 12 units. What is the width of the rectangle in units

Answer 1

2.4

Explanation:

Let the perimeter and the area = x.

L = 12

P = 2(L + W) = x

P = 2(12 + W) = x

A = LW = x

A = 12W = x

2(12 + W) = 12W

12 + W = 6W

5W = 12

W = 2.4

Answer: 2.4
