Question

The length of a rectangle is 4 yd longer than its width.

If the perimeter of the rectangle is 60 yd, find its length and width.
length: ?
width: ?

Answer 1

length: 17 yd

width: 13 yd

Explanation:

Let the width of the rectangle be x. This means the length will be x+4.

In this rectangle, 2 of the sides are x, and 2 are x+4.

If all the sides add up to 60, then we can make an equation: x+x+x+4+x+4=60

Simplify the equation to get 4x+8=60

Subtract 8 from both sides to get 4x=52

Divide both sides by 4 to get x=13

x is the width, so we know the width is 13.

The length is 4 more than the width, so we can add 4 to 13 and get 17.

The length is 17.
