What is the area of a rectangular field measuring 620 feet by 1280 feet in acres?

To find the area of a rectangular field, you multiply the length by the width. In this case, the dimensions of the field are 620 feet and 1280 feet.

First, calculate the area in square feet:

Area = Length x Width

Area = 620 feet x 1280 feet

Area = 793600 square feet

Next, to convert the area from square feet to acres, you need to know that one acre is equal to 43,560 square feet.

Now perform the conversion:

Area in acres = Area in square feet ÷ Square feet per acre

Area in acres = 793600 square feet ÷ 43560 square feet/acre

Area in acres ≈ 18.2 acres

Thus, the area of the rectangular field is approximately 18.2 acres. This is why the correct answer is identified as 18.2 acres.
