Answer:
Width=12 cm
Length=22 cm
Step-by-step explanation:
Let the width be x
Length= 2 cm less than twice the width
=2x-2
Perimeter of a rectangle=2(length+width)
68=2{(2x-2)+x}
68=2(2x-2+x)
68=2(3x-2)
68=6x-4
68+4=6x
72=6x
Divide both sides by 6
72/6=6x/6
12=x
Width=12 cm
Length=2x-2
=2(12)-2
=24-2
=22 cm
