Find the iength and width or a rectanguler lot with a perimeter of 88 meters if the length is 4 meters more than the width.

Use this formula:
P=2L%2B2w
Plug your amount for perimeter into the formula:
88=2L%2B2w
Since the length is 4 meters more than the width, L=w+4:
88=2%28w%2B4%29%2B2w
Use the distributive property for the parentheses:
88=2w%2B8%2B2w
Rearrange the terms:
88=2w%2B2w%2B8
Add the like terms together:
88=4w%2B8
Subtract 8 from both sides:
80=4w
Divide both sides by 4:
20=w

So, the width is 20. Since the length is 4 meters more than the width, the length is 24.
