Teaser and introduction goes here. Sample problem here.
Finding the area of parallelograms means you need to count the number of unit squares inside the parallelogram. This is a bit more difficult than the rectangle since the parallelogram cuts many of the unit squares into fractional pieces. However, we can rearrange the parallelogram into a more familiar figure without changing its original area. Then we can find the area of the familiar figure, which will have the same area as the parallelogram. |
In this parallelogram, you can cut the triangle from the left of the parallelogram and move it to the right side of the parallelogram, making a rectangle. We know the formula for finding the rectangle’s area is base • height, so the area of this shape is 8 • 5, which is 40 square units.
Basically, to find the area of a parallelogram you use the same formula as with rectangles.
A = base • height
A = bh
Notice that the lengths of the slanted sides of the parallelogram do not have any affect on the area of the parallelogram.
Find the area of this parallelogram. |
A = bh A = (5)(2) A = 10 u^2 |
Find the area of this parallelogram. |
A = bh A = (6)(3) A = 18 u^2 |
