So for the area of the square pyramid, it shows 15 feet and 9.9 feet
To find the area of a square pyramid, you need to calculate the sum of the lateral area (sides) and the base area.
Given that the side length of the square pyramid is 15 feet and the slant height is 9.9 feet, we can calculate the lateral area using the formula:
Lateral area = (1/2) * perimeter * slant height
First, calculate the perimeter of the base of the square pyramid:
Perimeter = 4 * side length
Perimeter = 4 * 15 = 60 feet
Now, calculate the lateral area:
Lateral area = (1/2) * 60 * 9.9
Lateral area = 297 square feet
Next, calculate the area of the base of the square pyramid:
Base area = side length^2
Base area = 15^2 = 225 square feet
Finally, add the lateral area and base area to find the total area of the square pyramid:
Total area = Lateral area + Base area
Total area = 297 + 225 = 522 square feet
Therefore, the total area of the square pyramid is 522 square feet.
