Question

The length of a rectangle is one foot more than twice its width. If the area of the rectangle is 300ft2, find the dimensions of the rectangle.

Answer 1

Answer:

12 ft x 25 ft

Step-by-step explanation:

If L is the length and W is the width:

L = 2W + 1

300 = LW

Substitute:

300 = (2W + 1) W

300 = 2W² + W

0 = 2W² + W − 300

0 = (2W + 25) (W − 12)

W = 12

L = 2W + 1

L = 25

The rectangle is 12 feet wide and 25 feet long.
