A monument in a park is shaped like a square pyramid. The dimensions are shown in the net. What is the surface area of the monument, including the base?

4 m²

12 m²

14 m²

24 m²

Area of pyramid = 14 square meter

Explanation:

Area of one right angled triangle (base) (height)

Put base m, height m

Area of one right angled triangle (2)(2.5) = 2.5 square meter

Area of 4 right angled triangles square meter

Area of square = side × side = 2 × 2 = 4 square meter

So,

Area of pyramid = 10 + 4 = 14 square meter
