The formula for the area A of the triangle is A=1/2BH, where B is the length of the base, and H is the height. Solve the equation for B.

I don't know how I'm supposed to be able to figure this out?

What numbers were you given? We can show you how to figure it out with a specific problem.
I think maybe what's being asked is to get an equation with B on the left-hand side.

A=(1/2)BH

multiply both sides by 2

2A=BH

divide both sides by H

2A/H = B

so

B = 2A/H
The formula for the area of a triangle is ​A=12bh​ where b is the base and h is the height.
