Final answer:
The height of the parallelogram is approximately 3.4 centimeters.
Step-by-step explanation:
The formula for finding the area of a parallelogram is A = BH.
Given that the area, A, is 15.3 square centimeters and the base, B, is 4.5 centimeters,
we can write the equation as 15.3 = 4.5H.
To find the height, H, we divide both sides of the equation by 4.5: H = 15.3 / 4.5.
Using a calculator, we find that H ≈ 3.4 centimeters.
