Question

Find the surface area of the pyramid represented by the net.

A net showing 4 triangles and a square. The square has a length and width of 4 meters and the triangles have a base of 4 meters and a height of 7 meters.

Answer 1

Explanation:

You have EIGHT triangles that have base 2 and height 7

area of triangle = 1/2 * b * h

eight of them : EIGHT * 1/2 * 2 * 7 = 56 m^2

PLUS one square that is 4 x 4 = 16 m^2

total = 56 + 16 = 72 m^2
