The area of a rectangle and a parallelogram can be calculated in the same way. Just multiply the base by the height! This simple trick works because a parallelogram can be rearranged into a rectangle.

Given an area of 24 units and a base of 6 units, we used this formula to find the missing height. The answer was 4 units. Isn't math fun? video https://cdn.kastatic.org/ka_thumbnails_cache/c702545c-0bbc-4ce1-9d2f-0c23c5a17d52_1280_720_base.png Finding height of a parallelogram In this lesson, we learned that the area of a parallelogram equals the base times the height.

For a triangle, the area is half of a parallelogram's, so it's calculated by multiplying the base by the height and then dividing by 2. video https://cdn.kastatic.org/googleusercontent/Fi9pR66SMMyijKzoyFIw6a2cHjUub-HncPLAlfT0a90llRBEciMFgGmv-CAlSSHoRNi9iIgUuqiBYzHBnwv9yt4 Area of a triangle The area of a rectangle and a parallelogram is found by multiplying the base by the height.
