A lot measuring 100 ft by 218 ft would be approximately how many acres?

To determine the size of a lot in acres, you'll first need to calculate the area of the lot in square feet and then convert that measurement into acres.

The area of the lot can be calculated by multiplying its length by its width. In this case, the dimensions provided are 100 feet and 218 feet. Thus:

Area = Length × Width Area = 100 ft × 218 ft Area = 21,800 square feet.

Next, to convert square feet into acres, it's essential to know that one acre equals 43,560 square feet. Therefore, to find the area in acres, divide the area in square feet by the number of square feet in an acre:

Area in acres = 21,800 sq ft ÷ 43,560 sq ft/acre ≈ 0.5 acres.

This means the lot measuring 100 feet by 218 feet is approximately half an acre in size, confirming that the correct choice is indeed half an acre.
