Perimeter of rectangles with mixed metric units

Working out the perimeter of a rectangle is simple—just add up the lengths of all the sides! But in real life, you might be measuring one side in centimetres and another in metres (like the length of a classroom versus the width of a table). That’s why it’s important to be confident converting between metric units while calculating perimeter. Jump to the questions
