Part a : Net A because when you fold it up it will look like the wanted prism

Part b : AB = 3 in
BC = 5 in
CD = 7.2 in

Part c : area of one triangle = 4*3 = 12 / 2 = 6
6 * 2 = 12 (because there are 2 triangles)
7.2 * 3 = 21.6
7.2 * 4 = 28.8
7.2 * 5 = 36
Add them all up : 12+21.6+28.8+36 = 98.4
So surface area is 98.4 in
