Let x cm is the width of a rectagular mailing label
The length of a rectagular mailing label is 4 centimeters less than twice the width, then the length is 2x-4 cm
The perimeter of a rectangle is P=2%28l%2Bw%29, where l is the length, w is the width
Equation 2%28x%2B2x-4%29=52divide by 2
3x-4=26
3x=26%2B4
3x=30
x=30%2F3
x=10cm is the width of a rectagular mailing label
The length is 2%2A10-4=16cm
