Answer:
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.
