Take the length of one side and multiply it by itself and that will be your answer
1. 5+4
2. 7+2
The answer is 9.
I hope I helped! :)
We have

so this is indeed a difference of squares. Factorizing would give

making the answer D.
We can further factor the first term here and write

but that's clearly out of the scope of this question.
42 I think. I'm sorry if I'm wrong.. Hope this helped!!
