The formula for finding the height in a parallelogram.

Use the base and multiply the base number by h which is the height. We are given the area so we have to multiply the base by a number which is height to equl the area.

A Parallelogram has a base of 90 and a height of 54. What is the area?

You have to do base times height and you get the area. You multiply 90 by 54 and you get the area.

A rectangle has a length of 23 and a width of 65. What is the area?

You multiply 23 by 65 which is base times height and you get the area.
