Question

When solving problems with composite figures, how do you know if you need to add the areas or subtract them?

Answer 1

Answer:

In composite figures the total area of the composite figure should be broken up into smaller area comprising of rectangles, squares, circle, semi-circles, right angle triangles, isosceles triangles and right angled triangles.

All the areas should be calculated separately and finally should be added to give the total area of the composite area,

The need for subtraction arises only if the dimensions of each smaller area are not given.
