The surface area of a triangular pyramid is 80 m2. if the pyramid is enlarged by a scale factor of 2, what is the surface area of the scaled image? 240 m2 640 m2 160 m2 320 m2

If the linear dimensions are enlarged by a scale factor k, the areas are enlarged by a scale factor k^2.

Here, the linear dimensions were enlarged by a factor of 2. Then, the area was enlarged by a factor of 2^2. 2^2 = 4, so multiply the original area by 4 to find the new area.

80 m^2 * 4 = 320 m^2
