Am I able to answer a question like this? (1 Viewer)

Basically for this question (and most other questions), my answers are in decimal place, and the answer is different, but if you were to put their answer in the calculator, it'll be the same as mine. Will I still get the answer right if I wrote it out like how I did in my book?

$Yes, just simplify your answer in exact form using $15^2 = 225$ and $\sin \frac{\pi}{3} =\frac{\sqrt{3}}{2}$. In fact, you should be leaving your answers in exact and simplified form, in general. Generally, you should only round the answer if they're asking for the area to a certain number of decimal places or sig. figs (or if the question is a money problem or number of years problem or physical application problem, in which case you'd give a numerical answer sometimes).$

So I shouldn't write the answer as 20.38?
