Answer:

146 [tex]ft^{2}[/tex]

Step-by-step explanation:

9x6/2 = 27

27x4 = 108

6x6 = 36

36+108 = 146

TRUE answer: 144 square feet
So one the triangle face of the pyramid has an area of 27 square feet ( 9 x 6/ 2)

Multiply that by 4 because there are 4 faces of triangles (27 x 4 = 108 square feet)

The area of the square base is 36, we get that by multiplying 6 by 6 (since the square has equal sides.

Add 108 and 36 then you get 144 square feet
