Nora has an orange rope and a green rope. The orange rope is 9 meters shorter than the green rope. The green rope is 12 meters long. How many meters of rope does Nora have in all?

15 m

Step-by-step explanation:

12-9=3 meters of orange rope

so 3 m of orange + 12 m of green

15m in total

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.
