Question

Whats the surface area of this figure

Answer 1

Answer:

504

Step-by-step explanation:

The area of the base is 14 x 14 which is 196

The area of one triangle is 1/2 x base length x height which is:

1/2 x 14 x 11 = 77

So the area of one triangle is 77. The area of all the triangles is the same and there are 4 triangles.

So the surface area is

196 + 77 + 77 + 77 + 77 = 504
