Area And Perimeter Irregular Rectangular Shapes Practice Activities
Printable Class 6 maths activities for finding area and perimeter of irregular rectangular shapes by splitting, combining, and checking side lengths.
Practice that builds confidence
Understanding irregular rectangular shapes
These Class 6 geometry worksheets help children practise finding the area and perimeter of irregular rectangular shapes, also called composite rectilinear shapes. Learners work with shapes made from joined rectangles and learn to reason about missing side lengths before calculating.
The printable activities include clear diagrams, labelled lengths, and varied layouts that require children to split shapes into rectangles, add areas, and trace the outside boundary for perimeter. The focus is on careful visual thinking, not just applying a formula.
Irregular rectangular shapes are made from straight horizontal and vertical sides, often by joining or removing rectangles. Children need to see that the shape is not solved in one step. For area, the shape can be divided into smaller rectangles. For perimeter, only the outside edge is counted, including any inward corners.
Building the method step by step
These worksheets guide learners from simple L-shaped figures to more complex rectilinear layouts. A child may split a shape into two rectangles, find each rectangular area using length × breadth, then add the parts. In other questions, a missing side must be found by comparing opposite horizontal or vertical lengths. This builds the habit of checking the diagram before writing numbers.
A parent routine that works
At home, ask your child to use a pencil to lightly draw a dotted line showing one possible split. Then have them label each new rectangle with its length and breadth, calculate each area, and add the results. For perimeter, encourage them to place a finger on one corner and move around the outside boundary, writing each side length in order. A quick final question—“Did you count any inside line by mistake?”—helps prevent a common error.
Classroom uses for teachers
Teachers can use these pages for geometry practice after introducing area and perimeter of rectangles. They work well for independent practice, maths centres, peer checking, or a short assessment of spatial reasoning. Students can compare different valid ways to split the same shape, which encourages mathematical discussion and shows that more than one strategy can lead to the same area.
Common errors to watch for
Children often add internal split lines to the perimeter, forget to find a missing side, or multiply all visible numbers together. Some may find area correctly but write the wrong unit idea, such as using square units for perimeter. Remind them that area covers the surface, while perimeter measures the distance around it.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The practice is designed to make children slow down and read the diagram. Varied shapes stop them from memorising a single layout, while repeated rectangular reasoning strengthens confidence. A child-friendly strategy is: “Split for area, walk around for perimeter, and check missing sides before calculating.”
Helpful answers
Frequently asked questions
What is an irregular rectangular shape in these worksheets?
It is a shape made only from horizontal and vertical sides, usually by joining rectangles or cutting a rectangle-like shape into an L, T, or step form. Children use rectangle rules to solve it.
How should my child find the area of these shapes?
They should split the shape into smaller rectangles, calculate the area of each rectangle using length × breadth, and then add the rectangular areas together.
How is perimeter different from area in these problems?
Area measures the surface covered by the shape and is given in square units. Perimeter is the total distance around the outside edge, so internal split lines are not included.
Why do some questions have missing side lengths?
Missing sides encourage children to compare opposite horizontal or vertical lengths. This helps them understand the structure of the shape instead of simply using the numbers shown.
What mistake should Class 6 students watch for most carefully?
The most common mistake is counting a line drawn inside the shape as part of the perimeter. For perimeter, students should trace only the outer boundary.
