Solve for area of a trapezoid

A= h(b1+b2)
2

Solve for b1

To solve for the area of a trapezoid given the height (h) and the lengths of the two parallel bases (b1 and b2), you can use the formula A = (h * (b1 + b2))/2.

Now, to solve for b1, we can rearrange the formula by isolating b1.

First, multiply both sides of the equation by 2 to get rid of the denominator:

2 * A = h * (b1 + b2)

Next, divide both sides of the equation by h:

(2 * A) / h = b1 + b2

Finally, subtract b2 from both sides of the equation to isolate b1:

b1 = (2 * A) / h - b2

Therefore, the formula to solve for b1 is b1 = (2 * A) / h - b2, where A is the area of the trapezoid and h is the height.
