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.

55.72 feet of fence

Step-by-step explanation:

Kaitlyn´s garden is square, so we know that all the sides are the same in a square and the formula to get the area of a square is:

x*x=A

x^2=A

where:

x is one of the sides

A is the area,

So we know that A=345 square feet, so:

x^2 = 345 square feet

x = √345

x=18.57 feet

We know that she is going to put a fence around three sides and each side is 18.57 feet, so we have to multiply the sides by 3:

18.57 feet * 3 = 55.72 feet

She will need 55.72 feet of fence
