1. To solve the problem, let’s convert millimeters to centimeters.
10 mm = 1 cm.
2. Find the width of the rectangle.
3 – 1 = 2 cm.
2. Now find the perimeter of the rectangle. The perimeter of the rectangle is determined by the formula: P = 2 · (a + b), where a, b are the sides of the rectangle. So we write the solution like this:
2 (3 + 2) = 10 cm.
Answer: The perimeter of the rectangle is 10 cm.
