Answer:
Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a by shape. We'll use Pythagorean Theorem to find the diagonal.
Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
A = L x W
L = W + 3
so equation
A = W (W + 3)
70 = W (W + 3)
or
W (W + 3) = 70
answer
D. last one
W (W + 3) = 70
