Emmy is playing with a calculator. She enters an integer, and takes its square root. Then she repeats the process with the integer part (round down) of the answer. After the third process, the integer part equals 1 for the first time. What is the difference between the largest and the smallest number Emmy could have started with?
(A) 229

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
