Answer:
585 m²
Explanation:
The surface area of the given pyramid is made up of 4 congruent triangles and a square base.
Area of a triangle = 1/2 × base × height
= 1/2 × 13 × 16
= 104 m²
Area of a square = (base edge)²
= 13²
= 169 m²
Total Surface Area = area of 4 triangles + area of base square
= (4 × 104) + 169
= 416 + 169
= 585 m²
