Lesson 18 Activity 2:

Measuring the Area of a Parallelogram


A parallelogram and a rectangle have much in common based upon their straight sides.

A parallelogram is a flat shape with opposite sides parallel and equal in length.

However, when you find the area of a parallelogram, it might be easier to first re-sketch your figure cleverly to help with the understanding.



As you can see, a parallelogram and a rectangle are very similar. A rectangle is a four-sided shape where every angle is right angle (90 degrees). As well, opposite sides of a rectangle are parallel (always the same distance apart) and are of equal length.

A parallelogram, on the other hand, has opposite sides that are parallel and equal in length. To find the area of a parallelogram, use the formula below.




Remember! Just like when you find the area of a rectangle, the area of a parallelogram is also in square units.
