Answer:
20 meters long and 10 meters wide
Step-by-step explanation:
since the perimeter is 60 and one side of it is 20 then you multiply 20 by 2, 40, to get both sides. Then you subtract 40 from 60 leaving the other two sides as 20, meaning that if you divide 20 by 2 you can find that the width of the dance floor is 10 meters long.

For finding the mean number of working TV sets, we need to <u>divide the total number of TV sets by the total frequency</u>.
Now for finding the total number of TV sets, first we will <u>multiply each number of TV sets by it's frequency and then sum up all the results</u>.
So, the total number of TV sets

and total frequency 
Thus, the mean number of working TV sets 
The swimming pool is a <span>rectangular prism</span> (which means it's a 3D rectangle). To find the volume of a rectangular prism you multiply Length x Width x Height.
In this case that would mean 16*10*8 (height and depth are the same in this problem).
16*10*8=<span>1280 ft</span>³<span>
