A = (1/2) b h
2A = b h
b = 2 A / h

A=1/2bh [b]
2A=bh (multiply both sides by 2 to get rid of 1/2)
(2A)/h=b (divide both sides by h)
Then just put in your numerical values of A and h and you will get b. A will be the area of triangle you are working with, h will be its height and b is its base.

A = 1/2bh cross multiply :: 2bhA = 1 :: b = 1/2hA

A = 1/2bh (multiplied both sides by 2)
2A = bh (divided both sides by h)
b = (2A)/h

It looks like you're working with triangles. The area of a triangle is
A = 1/2 (B)(H)
where A is the area, B the base, and H the height (many books say "altitude" here).
Rearranging to isolate B yields
B = 2 A / H

1. A = 1/2bh
2. Ax2= bh (that's A times 2)
3. (Ax2)/h (A times 2 all divided by h)
4. b= (2A)/h
hope it helps

Assuming you're given the figures for A and h, rearrange the equation to b = 2A/h, then solve for b.

Multiply both sides of the equation by 2 and divide both by h.
