Calculate the surface area of each pyramid with the following values. (P = perimeter, b = one side of the base, s=side, h=height). Number of sides is given in each problem.

1. P = 12 ft, s = 4 ft, b = 4 ft, h=2 ft, 3 sides (base is a triangle)

4. P = 45 yds, b = 15 yds, s=15, h=12, 3 sides (base is a triangle)

6. P = 15 ft, b = 5 ft, s=5 ft, h= 4, 3 sides (base is a triangle)

9. P = 45 yds, b = 15 yds, s=10, h=8, 3 sides (base is a triangle)

12. P = 45 ft, b = 15 ft, s=10, h=8, 3 sides (base is a triangle)

15. P = 27 yds, b = 9 yds, s=30, h=25, 3 sides (base is a triangle)
