The area of Kaitlyn's square garden is 345 square feet. One side of the garden is next to a shed. She wants to put a fence around the other three sides of the garden. Find three sets of approximations for the amount of fence it will take. Then determine how much fence she should buy.

well, my first thought was to divide the garden space by four, so you know how much each side would take, and then multiply it by three, so you have three sides. the answer was 258.75 feet of fence. Is that what you wanted??
