wikiHow Parallelogram Area Calculator To calculate the area of a parallelogram, you need to know the base and height of the parallelogram. The formula for the area of a parallelogram is: Area = base x height Here are the steps to calculate the area of a parallelogram: 1. Measure the length of the base of the parallelogram. This is the distance between two parallel sides of the parallelogram. 2. Measure the height of the parallelogram. This is the perpendicular distance between the base and the opposite parallel side of the parallelogram. 3. Multiply the length of the base by the height of the parallelogram to find the area. For example, let's say you have a parallelogram with a base of 6 units and a height of 4 units. To calculate the area of the parallelogram, you would do the following: Area = base x height Area = 6 x 4 Area = 24 square units Therefore, the area of the parallelogram is 24 square units. Page
