Exploring Perimeter with Composite Rectilinear Shapes

Learning objective

Learning Objective

Understand how to calculate the perimeter of composite rectilinear shapes using Year 5 math skills.

What do you already know about finding the perimeter of composite rectilinear shapes?

What is Perimeter?

Perimeter is the total distance around the outside of a shape. It is found by adding the lengths of all the sides together.

Rectilinear Shapes

Rectilinear shapes are polygons with straight sides. They can be composed of two or more rectangles joined together.

Composite Rectilinear Shapes

Composite rectilinear shapes are made up of two or more rectangles or squares. Finding the perimeter involves adding the lengths of all the sides.

Identifying Sides

To find the perimeter, identify all the individual sides of the composite shape and add them together.

Calculating Perimeter

Add the lengths of all the sides to find the perimeter of the composite rectilinear shape.
