What is the area of the base of a tank that is 20 feet wide and 40 feet long?

To determine the area of the base of a rectangular tank, you can use the formula for the area of a rectangle, which is length multiplied by width. In this scenario, the length of the tank is 40 feet and the width is 20 feet.

Calculating the area involves multiplying these two dimensions together:

Area = Length × Width

Area = 40 feet × 20 feet

Area = 800 square feet

This calculation shows that the area of the base of the tank is indeed 800 square feet, confirming that the answer is correct. Understanding this formula is crucial for various applications in sewage treatment where the size of tanks plays a significant role in design and capacity calculations.
