Hey there So you can find the answer by dividing 28/4 which will get you 7 so we now multiple 7 By three so that we can find what 3/4 of 28 is which equals 21 days so the sun didn't sine for 21 days.
Since this is a right triangle, you can plug it into Pythagoras theorem of a squared plus b squared equals c squared. So 198 squared plus 40 squared equals 40804. Square root this and it gives you 202 meters.
