b.) divide by 1/2
c.) divide by h
d.) divide by 1/2h

Option (a) is correct.

Multiply by

Step-by-step explanation:

Given : The formula for the area of a triangle is

We have to choose the incorrect step from the given options to rearrange this formula to find the base of the triangle.

Consider the given formula

Since, we have to find the base of triangle.

So we have to divide both side by

We get ,

Simplify, we have,

So, we can divide first by , h or

So, Incorrect is Multiply by
