For this lesson, we are going to go over area of parallelograms. A parallelogram, remember, is a polygon with two pairs of parallel sides. To find the area, we are going to do the base times the height; so it is the same formula as a rectangle or a square. Remember that the height has to be the length that is perpendicular to the base. So, it doesn't actually matter which side you label as the base, as long as the height is the length perpendicular to that base. This lesson also covers area of some complex figures. Their area is actually the sum of the areas of all of its non-overlapping parts.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
