PrepSwift Quant Tickbox Quiz #11 Question 16

Hello, I am confused on Question 16 of PrepSwift Quant Tickbox Quiz #11. The correct answer is C

Here is my logic:
The area of a parallelogram is equal to b*h.

According to Group 9 of Quant Mountain, the length of a side of a triangle increases as the angle increases.
Drawing out the parallelograms, you get something like this

The bases are the same, but the angles corresponding to the height are different. In the top parallelogram, h_1 corresponds to 80. In the bottom parallelogram, h_2 corresponds to 100. Since 100 is greater than 80, h_2 is greater than h_1.
Then, we compare 4h_1 to 4_h_2. We can remove the 4, comparing just h_1 to h_2.
h_2 is bigger than h_1, so the answer is B.

Where did I go wrong?

This is not correct. You can deduce this when both angles are acute, but that isn’t the case here. Also your second diagram is a bit misleading since it looks like 80 degrees is obtuse.
