A)9
B)4
C)3
D)6

1 answer

The perimeter of a rectangle is given by the formula P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

In this case, we know that the length is 3 feet. We also know that the total length of fencing is 24 feet. Using the perimeter formula, we can write the equation:

24 = 2(3) + 2W

Simplifying this equation, we have:

24 = 6 + 2W

Subtracting 6 from both sides, we get:

18 = 2W

Dividing both sides of the equation by 2, we find:

9 = W

Therefore, the width needs to be 9 feet for this to work.

The correct answer is A) 9.
