Question

Let w = width and 4 + w = length.

Which equation represents the situation?
✔ w(4 +w) = 60
Using the zero product property, the equation is
✔ (w + 10)(w - 6) = 0
.
What is the length of the rectangle?
10
yards

Answer 2

The length = 10 yd

Explanation:

The length is 4 more than the width, and the area is 60.

w(4 + w) = 60

4w + w² - 60 = 0

w² + 4w - 60 = 0

(w + 10)(w - 6) = 0

w + 10 = 0 or w - 6 = 0

w = -10 or w = 6

Width = 6.

w + 4 = 10

Length = 10.
