200 + 200 + 200 + 200 + 200 + 200 + 200 + 200 + 200 = 1,800
Answer: B) 684m
Step-by-step explanation:
From 9 to 27 is a 3 times increase, from 27 to 108 is a 4 times increase. So following the pattern, we can determine that it will increase 5 times, and fall another 540m in second 4. Then, we simply add all the numbers together to get the answer!
If the shape of the room is a square, then the square root of the sum of the squares of the the two adjacent sides will give the diagonal.
i.e.

Since the square root of the sum of the squares of the the two adjacent sides is 24.04 and not 18.79, therefore, the shape of the room is not a square.

70.13047293 because if I convert all the fractions to decimals and and some parentheses we get this: ((2 + 489.05357142857) /1.167)/6 and that is equal to 70.13047293.
