Best ResponseYou've already chosen the best response.0Lateral surface area is the sum of the areas of the sides (triangular) but not the base. So the 4 triangles' areas add up to 20. The slant height is the height of the triangular side (not the height of the pyramid  see the difference?) So you know the area of each triangle (calculate) and you know the height of each triangle. Get the length of the base, then the area of the base, then finish up.

Best ResponseYou've already chosen the best response.0Use the formula for area of triangle: 1/2 * base * height. Area is known, height is known, so you can calculate base. Okay? Come on, stop giving up. You can do this.
