Step-by-step explanation:
Two triangular ends Area of one = 1/2 b * h b =1.2 h =0.9 Area = 1/2 * 1.2 * 0.9 = 0.54 sq meters Area of 2 = 2 * 0.54 1.08
Area bottom
L = 3.5 m w = 1.2 Area = L * W Area = 3.5 * 1.2 Area = 4.2
Area Back
L = 3.5 W = 0.9 Area = 3.5 * 0.9 Area = 3.15
Area Slanted piece
L = 3.5 w = 1.5 Area = L * W Area = 3.5 * 1.5 = <u> 5.25</u>
Total = 5.25 + 3.15 + 4.2 + 1.08 = 13.68
The person above me is perfectly right! Just keep in mind that questions like these are asking for surface area. Questions with “how much to cover.. “ and showing dimensions of a 3d figure are all about surface area.
