Asquare pyramid has a base area of 36 ft. the pyramid's total surface area is 144 ft. what is the area of each triangular face?

108 ft (1)

54 ft (2)

36 ft (3)

27 ft (4)

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
