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
