Answer 1

Answer:

total area =2(2area of triangle + area of rectangle)

Answer 2

Answer:

Step-by-step explanation:

area of right angle triangle = 1/2 × base × height

there are four right angle triangle in this diagram and two rectangle,

area of 4 right angle triangle = 4(1/2 × base × height)

                                                  = 4(1/2×1.5×2.6)

                                                 = 2×1.5×2.6

                                                  =3.0×2.6

                                                  = 7.8 m²

area of 3 rectangle is = 3(l×b)

                                          = 3(5×3)

                                            = 45m²

surface area of the prism is =  (7.8 + 45) m²

                                                   = 52.8 m²
