Maxium points plz answer if you know only

XY=18 units

Step-by-step explanation:

Perimeter of the rectangule= 2B-->Base+2H-->Heigth

B=3x

H=2X+2

2·(3X)+2·(2X+2)= 64

6x+4x+4=64

10x=60

X=6--> Now we replace the variable x with numbers

2·(3·6)+2·(14)= 64--> Its correct

B=3X--> 3·6=18--> XY

H=2X+2=12+2=14

step-by-step explanation:

it is the one with the most keychains.

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.
