Two 7 x 7 squares overlap to form a 10 x 7 rectangle, as shown. What is the total area of the two regions in which the two squares do not overlap? This question can be answered without introducing a variable, however, **you must introduce a variable and show a full solution properly using the variable**.

I know how to do this without the variable, but I’m having trouble adding one.

Thanks for the help!

How can this be? If they overlap to form a 10 x 7 ? this is larger than the dimension of the squares.....the most they can overlap is 7

Okay, let x equal the overlapping area.

If the squares did not overlap, it would be a 14 x 7 rectangle, with an area of 98. But this has an area of 70.

x = 98-70 = 28

You are very welcome!

:P
