1. If the width is 1/3 of the length, then the length is 3 times more, that is, the width must be multiplied by 3:
150 x 3 = 450 (mm).
2. Now you can find the perimeter of this rectangle by adding two lengths and two widths:
2 x 450 + 2 x 150 = 900 + 300 = 1200 (mm).
Answer: The perimeter of this rectangle is 1200 mm.
