Question 124525
The area of a rectangle is 40.if the length is 6 more than the width, find the dimensions of the rectangle.<br><br>

Ok, so you know that {{{L=w+6}}}.<br><br>

Plug this and your known area into the formula for area of a rectangle which is:
{{{A=L*w}}}<br><br>

Here it is with the values plugged in:
{{{40=w+6*w}}}<br><br>

Multiply:
{{{40=w+6w}}}<br><br>

Add:
{{{40=7w}}}<br><br>

Divide both sides by 7:
5 5/7=w<br><br>

Just add 6 to that to find your length, which is 11 5/7.

And there's your answer.<br><br>

Check:
40=5 5/7+6*5 5/7<br><br>

Multiply:
40=5 5/7+34 2/7<br><br>

Add:
{{{40=40}}}
