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.
50.75
you multiply 14.50 times 3.5
the reason why it is 3.5 is because there are two half hours in one hour, and another half hour plus 15 minutes ( which is half of a half hour)
