Please help, i am so stuck.

- Math, please please help -
**PsyDAG**, Wednesday, March 26, 2008 at 12:01pmThe surface area for each square would be the side multiplied by itself, with the bottom square = x^2.

The second square's surface would be (x-3)^2.

From this, you should be able to determine how to calculate the third square's area.

Then sum these three terms.

I hope this helps. Thanks for asking.
