The length of the rectangle is 3 m. And the width is 1 cm. What is the perimeter of the rectangle?

First, let’s bring all units of measurement to a single one.
3 m = 300 cm.
Next, we write down the formula for finding the perimeter of a rectangle:
P = 2a + 2b, where a is length, b is width.
Find the perimeter of the rectangle if the length and width are known by the problem statement:
P = 2 * 300 + 2 * 1 = 600 + 2 = 602 cm.
Answer: The perimeter of the rectangle is 602 cm.
