Question

Fantastic Middle School is building a park, in the shape of a square, with an area of 256 square feet. How much fence do they need to buy to close in the park?

Answer 1

A = a^2.....where " a " is the size of 1 side
A = 256

256 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 256 = a
16 = a

so each side is 16 ft....now we find the perimeter
P = 4a....where " a " is the size of each side
P = 4(16)
P = 64.......so they will need 64 ft of fencing <===
