Final answer:
To solve the equation for h, multiply both sides by 2 to eliminate the fraction and then divide by b, resulting in the correct answer of h = 2a / b.
Step-by-step explanation:
To solve the equation a = (1/2)bh for h, you need to isolate h on one side of the equation. Start by multiplying both sides by 2 to get rid of the fraction:
2a = bh
Next, to solve for h, you divide both sides by b:
h = 2a / b
Therefore, the correct answer is a. 2a / b.
