Explanation:

Surface area = area of base + 4 * area of a triangular side

= 13^2 + 4 * 1/2 * 13 * 16

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
