Answer:
Halo!!! i wrote my answer below your epic btw
Explanation:
you first have to break up the surface of the shape into smaller shapes so that they are easier to work with. you then calculate all of the shapes and add them together. this can be used in the real world to find the area of houses when you need to find how much space an area of the house has.
PS:If u didnt learn to find surface area this way insert anything you want into the beggining sorry i dont know what youve been learning
