So i really suck at math. How do I find the area of a shape if it is not a perfect square, circle etc.?

Area is the amount of stuff in the object so with an irregular shape, the easiest way to find the area is to see if you can cut the shape up into seperate regular geometetric shapes, then find their seperate areas. the total area is the sum of all of the parts

sorry I can't be specific because you weren't specific enough and also because the formulas are normally for regular shapes
