Question

The length of a rectangle is 2 units more than the width. The area of the rectangle is 48 units. What is the width, in units, of the rectangle?

Answer 1

Answer:

6 units

Step-by-step explanation:

A = lw

l = w + 2

48 = lw

48 = (w + 2)w

48 = w² + 2w

0 = w² + 2w - 48

Quadratic equation results =

w = 6 or w = -8

But the measure could not be negative, therefore w = 6
