Answer 1

The lateral area of a square pyramid can be calculated using the formula LA = 0.5 * perimeter of base * slant height.

The perimeter of the base of the square pyramid is 4 * side length = 4 * 11.2 cm = 44.8 cm.

Now, calculate the lateral area:
LA = 0.5 * 44.8 cm * 20 cm
LA = 0.5 * 896 cm2
LA = 448 cm2

Therefore, the lateral area of the square pyramid is 448 cm2.
