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

To determine the area of a rectangular field, you multiply the length by the width. In this case, the field measures 620 feet by 1280 feet.

First, calculate the area in square feet:

Area = Length × Width

Area = 620 feet × 1280 feet

Area = 793,600 square feet.

Next, to convert square feet to acres, you need to know that one acre equals 43,560 square feet.

Now, divide the area in square feet by the number of square feet in an acre:

Area in acres = Area in square feet ÷ 43,560 square feet/acre

Area in acres = 793,600 sq ft ÷ 43,560 sq ft/acre

Area in acres ≈ 18.24 acres.

Rounding to one decimal place gives approximately 18.2 acres, making this the correct answer. Understanding how to perform these calculations is essential for aerial application professionals to estimate field sizes for effective spraying operations.
