Mean: 6

Median: 6

Range: 8

Step-by-step explanation:

Mean is found by adding up all the values in the set and dividing by the amount of numbers in the set (in this one there are 8) 2+3+4+5+7+8+9+10=48. 48 divided by 8 = 6.

Median is the number in the middle, when the numbers in the set are ordered from least to greatest. Since there are two middle numbers in this set we add them together and divide by 2. 5+7=12. 12 divided by 2 = 6.

Range is found by taking the largest number and subtracting the smallest number from it. 10-2=8.

X + 4 units 

4 x 4 = 16 units

112 - 16 units = 96 units divided by four (number of sides of garden) =

 24. X = 24

However to check 

24 + 4= 28

            x 4

            ___

            112 So X=24
