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:
-
Start with the area formula: \[ A = \frac{1}{2}hb \]
-
To eliminate the fraction, multiply both sides by 2: \[ 2A = hb \]
-
Next, solve for \( b \) by dividing both sides by \( h \): \[ b = \frac{2A}{h} \]
So the correct answer is: \[ b = \frac{2A}{h} \]
