Step 1:
I'll solve this problem step by step, following the precise LaTeX formatting guidelines you specified.

Step 2:
: Identify the given formula

- $$b_{2}$$ is the length of the other parallel side
The area of a trapezoid is given by the equation: Where:

Step 3:
: Rearrange the equation to isolate b_{2}

2A = h(b_{1} + b_{2})
Multiply both sides by 2:

Step 4:
: Subtract hb_{1} from both sides

2A - hb_{1} = hb_{2}

Step 5:
: Divide both sides by h to solve for b_{2}

b_{2} = \frac{2A - hb_{1}}{h}

Final Answer

This formula allows you to calculate the length of the second parallel side of a trapezoid when you know the area, height, and length of the first parallel side.
