First, we need to identify the shape of the bases of the prism. The net shows that the bases are triangles. Second, we need to find the area of one of the triangles. We can use the formula for the area of a triangle: A = 1/2 x base x height. The base is 5 cm and the height is 4 cm, so the area is 1/2 x 5 cm x 4 cm = 10 cm^2. Third, we need to find the perimeter of one of the triangles. We can use the Pythagorean theorem to find the length of the hypotenuse: c^2=a^2+b^2, where a = 4 cm and b = 3 cm (from the net). So, c^2 = 4^2+3^2=16+9=25, and c = 5 cm.
