We know that the length is 5 cm greater than it's width.
Then width must be "x" and length must be "x+5"

Using P=2L+2L

P=2(x+5)+2(x)

We also know that P=106cm
106=2(x+5)+2(x)
106=2x+10+2x
106=4x+10

Subtract 10 from both sides
(106)-10=(4x+10)-10
96=4x

Divide 4 from both sides
96%2F4=4x%2F4
24=x
Width=24 cm
Length=x+5=24+5=29 cm
