Question

Find the total area the regular pyramid.

T. A. =

Answer 1

`T.A = 16√(3)`

Answer 2

T.A. = 16√3 units²

Explanation:

∵ The total area = the area of the four faces

∵ The four faces are equilateral triangles with side length 4

∵ Area of the equilateral Δ = 1/4 s² √3

∴ T.A. = 4 × 1/4 × 4² × √3 = 16√3 units²
