We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:

We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.
Hence, we can write:


Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.
Only figure C is a regular polygon since it has all sides congruent and all angles congruent.
