Atriangular pennant has two sides that are 90 cm long each with an included angle of 25°. what is the area of this pennant? enter your answer as a decimal in the box. round only your final answer to the nearest tenth. cm²

After taking the test, I found that the correct answer is 1,711.6

I had originally wrote 1,711.7 because I believed it needed to be rounded. I'm not entirely sure why it was incorrect when rounded up.

Hope this helps!!
