You just find the area of the triangle, and do that times 4 that number. The formula for finding the area of a triangle is half the base times the height 3 * 9 = 27. So the area of the triangle is 27 and the area of all 4 of the triangles would just be 27 * 4 = 108. Now for the square. Formula for finding the area of a square is length times width which would be 6 * 6 = 36. So then you do 36 + 108 = 144
So the area of the net is 144M
