This is a simple, quick, no fuss foundation math tutorial to assist you learn how to calculate the area of a parallelogram. It is associated with this tutorial: http://www.ninetyeast.net/maths/foundation/measurement/how-to-calculate-the-area-of-a-parallelogram The previous tutorial (http://www.ninetyeast.net/maths/foundation/measurement/how-to-calculate-the-area-of-a-square) 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). This worksheet includes six exercises for you to work through in your own time in order to consolidate your understanding of how to calculate the area of a 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'.

Answers
Exercise 1.
Area = 5 units x 4 units = 20 square units.
Exercise 2.
Area = 5 units x 6.5 units = 32.5 units.

Exercise 3.
Area = 5.5 units x 6.5 units = 35.75 square units.
Exercise 4.
Area = 6 units x 7.75 units = 46.5 square units.

Exercise 5.
Area = 5 units x 6 units = 30 square units.
Exercise 6.
Area = 3 units x 6 units = 18 square units
