If we know that Laura's canvas is square, and one side is 22cm,
area of a square is l*w, with a special case of l=w
the area will be
A= l*w=22*22=484cm^2
also, Asquare is=l^2
x<=4
x is less than or equal to four
children less than or equal to four can ride the train for free
1 yard = 3 ft
Therefore 26 / 3 = 8 2/3
26 ft = 8 2/3 yds
