Area of a Parallelogram

by Alex
(Halifax)

Need help...

The area of a parallelogram is 252 cm2 and base is 42 cm. Use ALGEBRA to find the height of the parallelogram. Include your formula and units. Show all steps...



Karin from Algebra-Class says:

The formula for the area of a parallelogram is:
A = bh Area = base times height

So, you are given A = 252 & b = 42

Let's substitute:
A = bh
252 = 42h

Now, we'll solve for h

252/42 = 42h/42
6 = h

Therefore, the height is 6 cm.

I hope this helps.
