B) 136,5 f?
D) 151.5 ft?

A. 184.8ft2

Step-by-step explanation:

The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.

The base area is a square of 6ft by 6ft.

For the sides, area of a triangle is 1/2 x base x height

= 1/2 x 6 x 12.4 = 37.2m2

For the four triangles = 4 x 37.2 = 148.8m2

For the square base, area is 6 x 6 = 36m2

Total surface area = 148.8 + 36 = 184.8ft2
