Measuring Perimeter with Units Answer Key

In this worksheet, students find the perimeter of rectangles using a non-standard unit represented by soup cans. They count around all four sides to determine total length. This practical exercise introduces the concept of perimeter through visual and concrete examples. It helps students understand that perimeter measures distance around a shape and reinforces the relationship between side lengths and total measurement. The activity builds spatial awareness and foundational geometry skills using accessible, visual methods.
