Answer:
He pays $39.56
Step-by-step explanation:
If finding the discount, always divide the percent by 100.
25% = 0.25
52.75*0.25=13.1875
Because its money, round to hundredths place, $13.19

You are basically finding the hypotenuse of a triangle with side lengths of 120 yards and 120 yards.
Using the equation a^2 + b^2 = c^2, solve for c (hypotenuse) where a and b are the side lengths (120 yards).
a^2 + b^2 = c^2
square root(a^2 + b^2) = c
square root (120^2 + 120^2) = c
square root (120^2 + 120^2) = c
square root (14400 + 14400) =c
square root (28800) = 169.7, rounded up to 170 yards of fencing needed.
