Homework Help: math

Posted by Jane on Friday, March 1, 2013 at 5:20pm.

A rectanglar blacktop with a length of 5x and a width of 3x has been erected inside a rectangular field that has a length of 12x and a width of 7x.

What is the area of the part of the field that is not blacktop? (I believe the answer is 69x^2)

There is a circular fountain in the rectangular field that has a radius of 3x. What is the area of the part of the field that does not include the blacktop of the fountain? Factor your answer. (Please show me how to set up and solve) Thanks
