Areas of Composite Shapes
Find the areas of combined shapes made up of one or more simple polygons and circles
This is level 2; Using letters to show how the areas of composite shapes are calculated.
If the area of
a and the area of
is b then the area of this compound
shape is 2a - b. Find the simplest way of expressing the areas of these shapes:
