Answer:
x=13, A=169
P=4s, so you substitute P with 52 and you're left with 52=4a. You divide 4 to both sides of the equation and a(or x) equals 13.
A=s^2, so since your side(x) equals 13 you calculate 13^2 or 13×13, and A=169.
I think you use
xamount(1-.8)
.8 being 80% as a decimal.
1 being 100%
so .2 or 20% remaining multiplied by whatever amount.
