Simple Math Tutorial: How to Calculate the Area of a Parallelogram

The previous tutorial (ninetyeast.net/maths/foundation/measurement/how…) described how to calculate the area of a square and a rectangle:
1. to count the number of square units that fit into the shape
2. to multiply the width by the height.

Parallelograms are like squares and rectangles that have been pushed to the side. To calculate their area we can still use both of the above methods, however the first method is a little difficult with parallelograms because they do not have right angles (angles of 90 degrees) i.e. they cut diagonally across square units.

You'll see in this video that the second method is still possible (multiplying the width by the height).

If you'd like to practice your area calculations, check out this worksheet here: ninetyeast.net/maths/foundation/measurement/how…
