9. How to calculate the area of a Parallelogram?

Find the sum of all sides and divide by 4.

Add the base and height and square the result.

Cut the pieces so it makes a rectangle. Then Base x Heightb x h

Multiply the base and height and then divide by 2.

To find the area of a parallelogram, it is important to understand that the base (b) and height (h) only need to be multiplied to get the area, no need to divide by 2 or add and square the values. Summing all sides and dividing by 4 is not a correct method for finding the area of a parallelogram.

Explanation

To find the area of a parallelogram, it is important to understand that the base (b) and height (h) only need to be multiplied to get the area, no need to divide by 2 or add and square the values. Summing all sides and dividing by 4 is not a correct method for finding the area of a parallelogram.
