The formula for the area of a triangle 1/2bh=a. which of the following is not a possible first step to rearrange this formula to find the base of the triangle? 1/2h a. multiply by 1/2 b. divide by 1/2 c. divide by h d. divide by

Option A.

Step-by-step explanation:

The formula for the area of a triangle is

Using this formula we need to find the formula for base of the triangle. It means we need to isolate the variable b on the left side.

So, first we can divide the given equation by or h or .

Divide the given equation by 1/2.

Divide both sides by h.

So, the first possible step can be

(i) divide by 1/2

(ii) divide by h

(iii) divide by 1/2 h

Only the step multiply by 1/2 can not be the possible step to solve for b.

Therefore, the correct option is A.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
