Perimeter WORKSHEET

Suitable for Grades: 3rd Grade, 4th Grade
CCSS: 3.MD.D.8, 4.MD.A.3
CCSS Description: Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.

Perimeter WORKSHEET DESCRIPTION

The worksheet focuses on perimeter calculations, structured into three distinct sections to build understanding and problem-solving skills.

In Section A, students are asked to calculate the perimeters of a range of shapes, including regular polygons, using given lengths. This section reinforces their ability to apply standard formulas and work with different units of measurement, such as centimeters and millimeters.

Section B tasks students with determining the value of missing lengths of shapes based on their given perimeters.

Section C introduces challenges through a range of problem solving questions. Students explore different rectangles with the same perimeter, calculating with different metric units, working with compound shapes, and forming and solving equations involving perimeter and side length.
