Area of a parallelogram

Again think in terms of a rectangle (see area of a triangle).

Redraw

Redraw the parallelogram so it takes the shape of a rectangle

The left-hand triangle will fit exactly in the right-hand triangle.

Redraw again.

If you have your new rectangle its simply base times height to find the area

So the area of a parallelogram is…

Base x Height (like a normal rectangle).

Alternatively

It could also be redrawn as

Alternatively you could divide the parallelogram into 2 triangles and one rectangle but wouldn’t that be the long way around?

Then the area could be worked out as:

Triangle A + Rectangle B + Triangle C
