Which correctly shows the area formula for a trapezoid, A=1/2h (b1+b2), rearranged for the quantity of interest h?

To rearrange the formula, we need to isolate the variable 'h' on one side of the equation. The correct rearrangement of the area formula for a trapezoid is:

A = (1/2)h(b1 + b2)

First, we can multiply both sides of the equation by 2 to eliminate the fraction:

2A = h(b1 + b2)

Then, to solve for 'h,' we can divide both sides of the equation by (b1 + b2):

h = 2A / (b1 + b2)

Therefore, the correct rearrangement of the formula for the quantity of interest 'h' is:

h = 2A / (b1 + b2)

To rearrange the formula A = 1/2h (b1 + b2) for the height (h), we can follow these steps:

Step 1: Multiply both sides of the equation by 2:
2A = h (b1 + b2)

Step 2: Divide both sides of the equation by (b1 + b2):
2A / (b1 + b2) = h

Therefore, the formula for the height (h) of a trapezoid, rearranged from the area formula, is:
h = 2A / (b1 + b2)

To solve for the height (h) in the area formula for a trapezoid (A = 1/2h(b1 + b2)), we can rearrange the equation to isolate h.

First, let's rewrite the formula:
A = 1/2h(b1 + b2)

To begin rearranging for h, we'll start by getting rid of the fraction. We can do this by multiplying both sides of the equation by 2:
2A = h(b1 + b2)

Next, we want to isolate h, so we divide both sides of the equation by (b1 + b2):
2A / (b1 + b2) = h

So, the correctly rearranged formula for h is:
h = 2A / (b1 + b2)
