How many acres are in a rectangular field measuring 620 feet by 1280 feet?

To determine the area of a rectangular field measured in acres, you first need to calculate the area in square feet and then convert that into acres.

The area can be found using the formula for the area of a rectangle, which is length multiplied by width. In this case, by multiplying the dimensions of the field:

620 feet * 1280 feet = 793,600 square feet.

Next, to convert square feet to acres, it is important to know that one acre is equivalent to 43,560 square feet. Therefore, you would divide the area in square feet by the number of square feet per acre:

793,600 square feet ÷ 43,560 square feet per acre = approximately 18.2 acres.

Thus, the correct answer reflects accurate calculations of the area conversion, showing that the field indeed measures about 18.2 acres.
