Question

Suzanne wants to put a fence around her square garden. If the garden covers an area of 49ft^2, how many feet of fencing does she need

Answer 1

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`

Explanation:

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

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:
