A pyramid always have a number of slant triangles equal to the number of the sides of the base.
This means that a pyramid always have the number of face which is one more than the number of sides of the base.
Therefore, given that a pyramid has n number of sides of the base, the expression for the number of faces of the pyramid is given by
number of faces = n + 1.
The composite figure is made up of 2 rectangles.
Area of the top rectangle = 9 x 10 = 90 m²
Area of the bottom rectangle = 30 x 9 = 270 m²
Area of the figure = 90 + 270 = 360m²
Answer: Area = 360m²
