Answer:

The area for a square is given by:


A = x^2

And we can find the dimension for one side like this:


x = √(A)

Replacing we got:


x = √(49 ft^2)= 7ft

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:


P = 4x and replacing we got:


P = 4*7 ft = 28 ft

For this case we know that Suzanne want to put a fance around a square garden with an area of 49 ft^2
