Answer:
31.25 in²
Step-by-step explanation:
Surface area of triangular pyramid
Perimeter, P = 4s = 4 * 2.5 = 10 inches
Lateral surface area = 0.5 * P * height = 0.5 * 10 * 5 = 25 inch²
The base area = s² = 2.5² = 6.25 inch²
Hence, surface are ao triangular pyramid ;
Lateral surface area + base area
= 25 inches + 6.25 inch²
= 31.25 in²
