In a pyramid with a square base, if each side of the base is 10 meters, what is the perimeter of the base?

To find the perimeter of a square base, you can use the formula for the perimeter of a square, which is the length of one side multiplied by 4. In this case, since each side of the base of the pyramid is 10 meters, you would calculate the perimeter as follows:

Perimeter = 4 × length of one side

Perimeter = 4 × 10 meters

Perimeter = 40 meters

This confirms that the perimeter of the base is indeed 40 meters, making it the correct answer. Understanding the properties of a square, particularly that all four sides are equal and the straightforward calculation of the perimeter, is essential in this context.
