Question

The length of a rectangular poster is 7 in. greaterthan the width. The perimeter is 114 in. Find thewidth and length.

Answer 1

Let the width be x. The lenght is x+7

The perimetert is 2x +2(x+7)=114

2x + 2x + 14 = 114

4x + 14 = 114

4x=114-14

4x=100

x=25

So, the width is 25 and the lenght is 32.
