Please help! A parallelogram has an area of 396 square centimeters and a height of 18 centimeters.

frosja888 [35]

The area formula for a parallelogram is base*height=area. Make an equation. You know the area and the height, so plug that into the equation, and you get x*18=396. Solve for x by dividing 396 by 18 and you get 22. So, the base is 22cm.
