What is the approximate area in square feet that will be treated around a rectangular building measuring 72 feet by 45 feet with a swath 4 feet wide?

To determine the area that will be treated around the rectangular building, first, calculate the total dimensions of the treated area. The building measures 72 feet by 45 feet, and a 4-foot-wide swath will surround it.

Start by adding 4 feet to each side of the building's dimensions to account for the swath. This results in:

• Length: 72 feet + 4 feet (on one side) + 4 feet (on the other side) = 80 feet
• Width: 45 feet + 4 feet (on one side) + 4 feet (on the other side) = 53 feet

Next, calculate the overall area of the building plus the treated area:

80 feet (length) x 53 feet (width) = 4,240 square feet

Now, calculate the area of the building itself:

72 feet (length) x 45 feet (width) = 3,240 square feet

To find the area that will actually be treated, subtract the area of the building from the total treated area:

4,240 square feet (total treated area) - 3,240 square feet (building area) = 1,000 square feet

This calculation indicates
