Question

The length of a rectangle is 8 inches longer than 3 times its width. The area of the rectangle is 156 square inches.

What is the width of the rectangle?

Answer 1

The Answer:

Width = 6

Explanation:

Let width be w

(3w + 8) x w = 156

3
`w^(2)` x 8n - 156 = 0

(w + 8 x 6) (w-6) = 0

w = 6
