Answer 1

444 in

Hope this helps!

Explanation:

Area of a triangle is
`(1)/(2)` × B × H

Already given, the base is 12 and the height is 12.5,
`(1)/(2)` and 12 can simplify to get 6 so 6 × 12.5 is 75. One triangle has the area of 75, the 4 triangles have a total area of 300.

The base is a square, so the formula for that is L × W, which would be 12 × 12 = 144. Add that to 300 and the surface area of the pyramid is 444.
