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

A: Multiply by 12

The 1/2 is already multiplied by the bh, so in order to "undo" that multiplication, you have to do the opposite, which is to divide.
