Golfer had the lowest number of strokes per hole is <u>Alicia </u> = 4.
<u>Step-by-step explanation:</u>
We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find , Which golfer had the lowest number of strokes per hole :
<u>Rory:</u>
Number of strokes per hole = 
<u>Alicia:</u>
Number of strokes per hole = 
<u>Rickie:</u>
Number of strokes per hole = 
∴ Golfer had the lowest number of strokes per hole is <u>Alicia </u> = 4.
Let the width of room be =x mtrs
Then the length is x+2 mtrs
As Perimeter = 2(l+b) = 2(x+x+2)
16 = 2 ( 2x+2)
16/2 = 2x +2
8=2x+2
2x= 8-2 = 6
x = 6/2 =3 mtrs
Therefore width of the room is 3 mtrs
