The answer is 27 m² and 9 m² of blue and brown fabric will be used respectively.
A square pyramid is a three-dimensional shape that has a total of four triangular faces.
A most famous example of such a pyramid in real life is the Great Pyramid of Giza.
The sides are triangular faces are 3 m and 4.5m
Height of the prism is 4.5m and the side of the square base is 3m
The surface area for triangular face is (1/2) * base * height
= (1/2) * 3 * 4.5
= 6.75 m²
For four faces the surface area of the blue fabric required is side * side
= 4 * 6.75
= 27 m²
For the base , brown fabric is being used and the surface area of the base is
= 3 * 3
= 9 m²
Therefore 27 m² and 9 m² of blue and brown fabric will be used respectively.
