"A rectangular parking lot at the mega-mall is 7/10 mile long and 1/4 mile wide. How much fencing is needed to enclose the lot?"...

This question is essentially asking to solve for the perimeter. The formula for the perimeter of a rectangle is:

`2(l+w)`

Input the information we already know:

`2(7/10+1/4)`
Find A common denominator.

`2(14/20+5/20)`
Simplify.

`2(19/20)`

`2/1(19/20)`

`38/20`
Reduce to Lowest Terms.

`=19/10`
or

`=1 9/10`

1 9/10 miles of fencing will be required to enclose the entire lot.

Hope this helps.
