The area of the composite solid in the image given is: 399.6 m².
<h3>What is the Surface Area of a Composite Solid?</h3>
The surface are of the composite solid = area of the 3 triangular face of the top solid + area of the triangular base of the bottom solid + 3(area of rectangular face of the bottom solid).
Area of the 3 triangular face of the top solid = 3(1/2bh) = 3(1/2 × 8 × 7) = 84 m²
Area of the triangular base of the bottom solid = 1/2bh = 1/2 × 8 × 6.9 = 27.6 m²
3(area of rectangular face of the bottom solid) = 3(length × width) = 3(12 × 8) = 288 m²
Surface area of the solid = 84 + 27.6 + 288 = 399.6 m²
