W=width; L=length=3W;P=perimeter=44cm
P=2(L+W)
44cm=2(L+W)...Divide each side by 2
22cm=L+W...Substitute for L
22cm=3W+W
22cm=4W...Divide each side by 4
5.5cm=W...ANSWER 1: The width is 5.5cm.
L=3W=3(5.5cm)=16.5cm... ANSWER 2: The length is 16.5 cm.
CHECK:
Perimeter=2(L+W)
44cm=2(16.5cm+5.5cm)
44cm=2(22cm)
44cm=44cm
