Step-by-step explanation:
draw the net
there are 3 squares, each with a L = 5m and W = 1.5 +1.5m
2 triangles with a base of 1.5 + 1.5 and a height of 2.6m
Area of a rectangle = L x W
" " Triangle = 0.5 x b x h
so youd write and solve 3 rectangles x ( 5 m x 1.5 + 1.5) + 2 triangles x (0.5 x (1.5 +1.5) x 2.6m)
also look up the equation for surface area for this shape. Should give you the same thing. This method makes it more intuitive
