A triangular pyramid is a pyramid having a triangular base. It has 4 faces, 6 edges and 4 vertices.

Since the area of one face is 25 in^{2}

Therefore, surface area of triangular pyramid = 4 \times area of one face

= 25 \times 4

= 100 in^{2}.

So, the surface area of triangular pyramid is 100in^{2}.

Therefore, color is red.
