Answer 1

Answer:

• 84 cm²

Step-by-step explanation:

Total surface consists of 2 right triangles and 3 rectangles.

Sum of their areas is the total surface area.

Area of 2 triangles:

• A = 2*(1/2)*4*3 = 12 cm²

Area of 3 rectangles:

• A = 6*(3 + 4 + 5) = 6*12 = 72 cm²

Total surface area:

• S = 12 + 72 = 84 cm²
