parallelogram.

-------------------------

The previous tutorial (http://www.ninetyeast.net/maths/foundation/measurement/how-to-calculate-

the-area-of-a-square) reviews how to calculate the area of a square:

1. to measure the number of square that fit into the shape; and

2. to multiply the width and the height of the shape.

Parallelograms are like squares that have been pushed to the side. Both methods can be used to

calculate its area, but you'll know from the video associated with this worksheet (see above) that the

second method is usually more useful. Below are four exercises you can work through to consolidate

your learning. For the purposes of this worksheet, we'll stick to the generic 'square unit'.
