Allison and justin father donated $3 for every lap they swam in a swim athon allison swam 21 laps and justin swam 15 laps how much money did their father donate

Well it can be solved really easily. Firstly we will calculate for Allison. So Allison swam 21 laps in the swam athon so that means his father had to pay 3$ for every lap which means in the end he paid a total of 3 * 21 = 63.

Now as justin swam 15 laps in the swam athon so that means his father had to pay 3$ for every lap which means in the end he paid a total of 3 * 15 = 45.

So a total of 108 $ combined was paid by both of their fathers.

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.
