Shawn has 186 feet of fencing and plans to make a pig pen that is 15 feet wide. How long will the pig pen be?

Remember the formula for perimeter is [tex]P = 2l + 2w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.

Answer :

Final answer:

The length of the pig pen will be 78 feet.

Explanation:

To find the length of the pig pen, we can use the formula for perimeter: P = 2l + 2w. In this case, the width (w) is given as 15 feet. We know that the perimeter (P) is equal to 186 feet. Plugging these values into the formula, we can solve for the length (l).

186 = 2l + 2(15)

186 = 2l + 30

2l = 156

l = 78

Therefore, the length of the pig pen will be 78 feet.
