Sarah has a wall hanging in the shape of a parallelogram. What is the height of the wall hanging if its area and base are 300 square centimeters and 20 centimeters respectively?

Use the formula

Area = base times height.

You're given that area = 300cm^2 and base=20 cm.

Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.

So, h = 300/20

Simplify for an answer of 15.
