The area of a trapezoid is calculated using the formula below, where A is the area of the trapezoid, b1 and b2 are the bases of the trapezoid, and h is the height of the trapezoid. Rewrite the formula to find the base b2.

2 (/frac{Area}{h}) - b1 = b2

Step-by-step explanation:

The formula for calculating the area of a trapezoid is the following.

Area = / frac{b1+b2}{2} * h

What we are asked to find is the formula for finding b2. We can do this by rearranging the Area formula and getting b2 by itself on one side.

Area = / frac{b1+b2}{2} * h

/frac{Area}{h} = / frac{b1+b2}{2} ... divide h on both sides

2 (/frac{Area}{h}) = b1+b2 ... multiply 2 on both sides

2 (/frac{Area}{h}) - b1 = b2 ... subtract b1 on both sides

Now we have b2 by itself on one side and the formula is rewritten to solve for b2.
