The sides of a square-shaped room are 2 meters long. Carla wants to buy carpet to cover the floor of the room. If the carpet costs $64.00 per square meter, how much will it cost to buy enough carpet for
the room

the answer is $256

Step-by-step explanation:

I say this because 2 meters is 4 square meters then just multiply 4 by $64 and there is your answer.

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.
