The formula for finding a triangle's area is 1/2bh or bh/2. b is the base, h is the height. The problem would be very hard if you do not know the height. If you did, here is an example problem.

h = 3 and your area is 12

Fill in the missing parts.

b3/2=12

You multiply 12 by 2, canceling out the /2.

You are left with b3 = 24

Since b3 is b times 3, you divide 24 by 3 to cancel out the multiply by 3

The answer to that problem would be 8.
