Answer with explanation:
Factors of -36 are
It is given that , among the factors of , -36 , one factor is 11 less than half of the other factor.
If you will take, 
, then you can find such pairs.
Pairs are= (3,-4), (9, -1),(-1, -6),
<span> all of our square numbers from 1 to 80 are 1, 4, 9, 16, 25, 36, 49, 64. </span>
Area of lower rect + area of upper + 4 * sides rect areas
lower = upper rect
2 * rect1 + 4 * rect2
Area = 2 * 6 * 11 + 2 * 11 * 9 + 2 * 9 * 6 = 438 ft^2
or simply just take 2 ( and multiply each two sides.
D. I think because you would get a negative
