To find the perimeter of a rectangular tank, the formula used is the sum of all the sides, which can be expressed mathematically as:

Perimeter = 2 * (length + width)

In this scenario, the length of the tank is 10 feet and the width is 5 feet. Plugging these values into the formula gives:

Perimeter = 2 * (10 feet + 5 feet)

= 2 * (15 feet)

= 30 feet.

Thus, the perimeter of the rectangle is 30 feet.

The correct selection aligns with the calculated perimeter, confirming that the operation and understanding of the formula are accurate.
