Now here's a difficult area question for you

We know total area is 16, so lets base our equations on that.

Area Sq1:2.0 miles * [ x + (x - 1)] --> 2 * (2x - 1)

Area Sq2:1.2 miles * x

Area Sq1 + Area Sq2 = 16:

2 * (2x - 1) + 1.2x = 16

        4x - 2 + 1.2x = 16

                     5.2x = 18

                          x = 45/13 (exact answer) or 3.46 (rounded)

OP here.

Just want to say, oh thank you so so so much for not only answering, but also explaining it.  3.46 was indeed correct, and I can finally move on on this assignment.  c:
