Let’s split the parallelogram
Think back to your work in previous chapters. When you needed
to find the total area of a shape you were unfamiliar with, you split
your shape up into other simpler shapes you were more familiar
with.
If you look carefully, you’ll see that the parallelogram is actually
made up of a central rectangle, with a right angle triangle on either
end. This means that to find the area of the parallelogram, we can
find the areas of these shapes, and then add them up together.
You can split a parallelogram into
a rectangle and two triangles.
