Alex is building a rectangle fence around his yard. the total perimeter of the fence is 68 feet and the area of his yard is 240 square feet. based on this information, what are the dimensions of the fence? select one: a. 4 feet by 10 feet b. 8 feet by 15 feet c. 10 feet by 24 feet d. cannot be determined from the information given.

Let's call the length of the rectangular fence and the width of the rectangular fence .

Based on the information in the problem, we can make two equations, based on the formulas for perimeter and area:

Now, let's substitute in the values we are given in the problem:

Now, let's solve the system using substitution.

and

We are given two possible lengths. However, the funny thing is that both produce the same dimensions: 24 ft by 10 ft:

Thus, our answer is Choice C, or 10 feet by 24 feet.

d is the only accurate one
