James used the numbers shown to write a 5 digit number on the board where the value of the 3 is 1/10 the value of the digit 3 in the number 234.89. what would be the number that James wrote on the board? 2 3 4 8 9​

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
