The surface area of the pyramid is

Answer 1

calculated by finding the sum of the area of all four triangular faces.

Each triangular face of the pyramid has a base of 10 meters and a height of 20 meters. The formula to calculate the area of a triangle is 1/2 * base * height.

Area of one triangular face = 1/2 * 10 * 20 = 100 square meters

Since there are four triangular faces, the total surface area of the pyramid is:

100 + 100 + 100 + 100 = 400 square meters

Therefore, the surface area of the pyramid is 400 square meters.
