Question 152098
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+2w}}}

Plug your amount for perimeter into the formula:
{{{88=2L+2w}}}

Since the length is 4 meters more than the width, L=w+4:
{{{88=2(w+4)+2w}}}

Use the distributive property for the parentheses:
{{{88=2w+8+2w}}}

Rearrange the terms:
{{{88=2w+2w+8}}}

Add the like terms together:
{{{88=4w+8}}}

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.<br><br>
