Give an exact answer (do not round).

Answer 1

Answer:

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 =                                                   5.25

Total  = 5.25 + 3.15 + 4.2 + 1.08 =                               13.68
