Step-by-step explanation: First, get rid of the fraction by
multiplying both sides of the equation by 2.
That gives us 2A = bh.
Don't be thrown off by the capital A in this problem.
Just treat it like any other variable.
To get b by itself on the right side of the equation, we now simply
divide both side of the equation by h and our answer is 2A/h = b.
Take a look back at the formula now in the original problem.
Does it look familiar?
It's the formula for the area of a triangle.
Take a look at the image I have provided below.
I have made the "b" purple so you
can see that we are solving for it.
