Question

2) The length of a rectangle is 6 feet more than the width. The perimeter is 100 feet. Find the

length and width.

Answer 1

L=28 W=22

Explanation:

28+22=50

50*2=100

28-22=6

Answer 2

The length is 28 and the width is 22.

Explanation:

The formula for the perimeter of a rectangle is 2(l + w) = P. If the perimeter is 100 and the length is 6 feet more than the width, the equation can be written as 2( (w + 6) + w) = 100, or 2(2w + 6) = 100. You can then solve for w.

2(2w + 6) = 100

2w + 6 = 50

2w = 44

w = 22

If the length s 6 more than the width, the length s 22 + 6, or 28.
