Answer:
49 feet
Explanation:
If we turn this into an equation, we know that the perimeter of the fence, or P, is going to equal 2 times the width, x, and 2 times the length. We also know that the length is equal to the width+2, making the equation P=2x+2(x+2). Since the total perimeter of fencing is equal to 200 feet, we can change this equation to 200=2x+2(x+2). Then you can just solve the equation for the answer.
