What is the result in acres for a lagoon primary cell that measures 400 feet by 150 feet?

To determine the size of a lagoon primary cell in acres, you first need to calculate the area in square feet and then convert that area into acres.

The area of the lagoon can be calculated using the formula for the area of a rectangle:

Area = Length × Width.

For the given lagoon, the dimensions are 400 feet (length) and 150 feet (width).

Calculating the area:

Area = 400 feet × 150 feet = 60,000 square feet.

Next, to convert square feet into acres, you use the conversion factor where 1 acre is equal to 43,560 square feet.

To convert the area from square feet to acres, you divide the total area in square feet by the number of square feet in an acre:

Area in acres = Area in square feet ÷ 43,560.

Now substituting the values:

Area in acres = 60,000 square feet ÷ 43,560 square feet/acre.

Calculating that gives:

Area in acres ≈ 1.38 acres.

This calculation shows that the lagoon primary cell's area is approximately 1.38 acres, which corresponds to the given answer. Understanding these calculations is essential for environmental management
