I do not know what to answer here, you did not include the question itself.
Answer:
a)59.125, b)67.5, c)None
Step-by-step explanation:
Mean = All values added up and divided by the number of values

Median = Put all numbers in order from least to most and use the middle one, if there are two, use the mean of those two
. The middle ones are 60 & 75 so 
Mode = The number that repeats more times. In this case none of them repeat.
Square root of 289 = 17 ft
so this rug would not fit the room because one side is 16 ft long.
If we take the perimeter of the park as being equivalent to the distance that Anwar walks, then we can calculate the number of blocks he walks and then multiply this by the width of each block, thus:
Number of blocks walked = 1 + 2 + 2 + 1 + 1 + 1 = 8
Distance walked = 8*300 = 2400 feet
(You could also draw a diagram to help present this in a visual way but it is not necessary)
-4x +12 -12 = -4 -12
-4x = -16
x = 4
