Suppose a square garden represented by 16x squared foot squared what is the length of each side

4

Step-by-step explanation:

Area of a square is side*side, which is s^2

So, s^2=16

s=squareroot(16)=4

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.
