Step-by-step explanation:
This question is actually easier than you think, but I am here to help.
First off you know the room is a square. All squares have equal sides no matter what, that is the number 1 basic rule. (27ft by 27ft)
1. Find the area of the square: To find area you multiply Length by Width. Since you are multiplying two units you will get a squared value. The square measures 27 ft by 27 ft on both sides.
Lets multiply those two numbers:
We need to stay in the same unit because you are multiplying two values of the same unit. The total square feet of the room is
2. Next, all you need to do is convert to
Like you mentioned:
Now lets create a proportion between the two unit:
The unit cross cancels and your left with
.
Now all you do is multiply straight across and you get
