Calculate the perimeter of a rectangle with a length of 22.5 cm and a width of 47.0 mm.

Change to a uniform measurement, i.e., from cm to mm, or vice-versa

In this case, we will change the millimeter measurement to centimeters

So, width = 47 mm, or 4.7 cm, and the length stays at 22.5 cm

Perimeter of rectangle = 2L + 2w

Perimeter of rectangle = 2(22.5) + 2(4.7) = 45 + 9.4 = cm
