Question

This figure is a tetrahedron. What is the area of its base?

Answer 1

answer:

Because a tetrahedron is a Platonic solid, it has formulas you can use to find its volume and surface area. In both these formulas, the a stands for the length of one of the sides of a tetrahedron. Because the tetrahedron is made up of four equal equilateral triangles, all its edges are the same length.
