Perimeter = 222 millimeters
Length = 60 millimeters
Width = ?
The relationship between the quantities of the rectangle is given as;
Perimeter = 2 (Length + Width)
Inserting the values and solving for width
222 = 2 (60 + Width)
222 = 120 + 2 Width
2 Width = 222 - 120 = 102
Width = 102 / 2
Width = 51 millimeters
