<h3>
Area </h3>
Area is the amount of space that is occupied by a two dimensional shape or object.
From the diagram
Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²
Area of square = length * length = 2 m * 2 m = 4 m²
Surface area of monument = 4(2.5) + 4 = 14 m²
The surface area of the monument shaped like a square pyramid is 14 m².
