Question

A rectangle's length, x, is 2 meters greater than its width. If the perimeter of the rectangle is greater than 112 meters, what is the rectangle's possible length, x, in meters ?

Answer 1

The possible length is greater than 29 meters.

Explanation:

If the length is x then the width is x - 2 m.

So the perimeter is 2x + 2(x - 2) = 4x - 4 m.

4x - 4 > 112

4x > 116

x > 29 m.
