Thank you for the opportunity to help you with your question! Hope your day is going well!

The answer is no.

Step 1

The first goal is to find out what the length and width is. You take the square root of of 324 yrds^2= 18 yards.

Thus the L=18 yards and the W=18 yards

Step 2

You use the perimeter formula, since fences fit the outside of the pen.

Perimeter= 2(W)+2(L)

We find that the perimeter is 72 yards.

Step 3

Convert yards to ft.

1 Yard=3 feet.

Thus it is necessary to have 216 ft of fencing to complete the project.

Step 4

We only had 200 ft of fencing, which is not enough since 216 is bigger than 200. We are 16 ft shy.
