Can someone explain or show me how to do this problem: Mr. Cafagna wants a fence around the rectangular field that measures 24 ft by 36 ft. How many yards of fencing does he need?

24 + 36 + 24 + 36

The answer is 120 then I divide by 3 and get 40

yes

To calculate the amount of fencing needed, you need to determine the perimeter of the rectangular field. The perimeter is the total distance around the shape.

Here's how you can solve this problem:

1. Determine the dimensions of the rectangle: The length of the field is 24 ft, and the width is 36 ft.

2. Calculate the perimeter: The formula to calculate the perimeter of a rectangle is P = 2(l + w), where P is the perimeter, l is the length, and w is the width. In this case, P = 2(24 + 36) = 2(60) = 120 ft.

3. Convert the measurement to yards: Since the question is asking for the amount of fencing in yards, you need to convert 120 ft to yards. There are 3 feet in a yard, so divide the length in feet by 3 to get the length in yards. In this case, 120 ft ÷ 3 = 40 yards.

Therefore, Mr. Cafagna needs 40 yards of fencing to enclose the rectangular field.
