Marian wants to build a fence around a square garden in her backyard.  If the area of he garden is going to be 225 ft2, how much fencing, in ft., does Marian need?

Area of a square =  side^2

 

225 ft^2    = side^2                take the positive square root of both sides

 

sqrt ( 225 ft^2)  =  sqrt  (side^2)

 

15  ft =  side

 

And the perimeter of a square  =  4*side  = 4*15  =   60  ft needed
