Question

The area of a triangle can be found using the formula: A = 1/2 hb

Solve the area formula for b.

(1 point)

b=2 (A - h)

b = A/2h

b=2A/h

1/2b=A/h

Answer 1

To solve the area formula \( A = \frac{1}{2}hb \) for \( b \), we need to isolate \( b \). Here’s how to do it step-by-step:

1. Start with the area formula:
\[
A = \frac{1}{2}hb
\]

2. To eliminate the fraction, multiply both sides by 2:
\[
2A = hb
\]

3. Next, solve for \( b \) by dividing both sides by \( h \):
\[
b = \frac{2A}{h}
\]

So the correct answer is:
\[
b = \frac{2A}{h}
\]
