Answer:
Surface area = 39 yards²
Step-by-step explanation:
∵ the surface area of the pyramid = 1/2 pl + base area
Where p = perimeter of the base , l = slant height
∵ Area of the base = 3 × 3 = 9 yards²
∵ Perimeter of the base = 4 × 3 = 12 yards
∵ Slant height = 5 yards
∴ The surface area = 1/2 × 12 × 5 + 9 = 39 yards²
35
