I believe it would be 44.75 sq yards
The question is, "how many ways ...".
There are as many ways to solve a math problem as you can think of. (Some are shorter or easier than others.)
Essentially, an infinite number.
(7+x)+x=15
I did trial and error to get x=4.
1. 15*15= 225
2. 8*8= 64
3. 225+64= 289
4 . 17*17=289
