Question

How do I find the surface area of a composite figure? I've been struggling at this and it's been really hard on me and has also made me very upset. I use a schooling program called acellus and it doesn't really explain this stuff too well.​

Answer 1

An easy way to find the surface area of a composite figure is to divide the composite figure up into smaller shapes whose area it is easier to find. It is best to divide a composite figure up into a figure composed of many triangles and rectangles. Then, one will find the area of each of these smaller figures and add the value up to find the total surface area of the composite figure.
