Question

Here is the area formula for a trapezoid: A= 1/2 h (b1+b2)

Rearrange the formula to solve for h.

h= b1+b2/2A

b1= 2A/b1+b2
h= 2A/b1+b2
h is equal to the fraction with numerator 2 cap A and denominator b sub 1 plus b sub 2

h= 1/2 A (b1+b2)

Answer 1

To solve for \( h \) in the formula for the area of a trapezoid, \( A = \frac{1}{2} h (b_1 + b_2) \), we can rearrange the equation as follows:

1. Multiply both sides by 2 to eliminate the fraction:
\[
2A = h(b_1 + b_2)
\]

2. Next, divide both sides by \( (b_1 + b_2) \) to isolate \( h \):
\[
h = \frac{2A}{b_1 + b_2}
\]

So the correct answer is:

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