Question

The formula for the area of a triangle is 1/2bh=A. Which of the following is not a possible first step to rearrange this formula to find the base of the triangle?

A. Multiply by 1/2
B. Divide by 1/2
C. Divide by h
D. Divide by 1/2h

​

Answer 1

We want to put b alone on one side of the equation.

If we multiply by 1/2, we get 1/4bh = A/2. Not only did we not remove a variable from the left side, we made it even more complicated.

So the answer is A.
