Perimeter of Rectilinear Shapes WORKSHEET DESCRIPTION

This worksheet builds fluency in finding the perimeter of rectilinear shapes, progressing from simple composite figures to more challenging reasoning problems.

Section A introduces learners to the perimeter using shapes drawn on square grids, supporting visual understanding and straightforward counting of side lengths.

Section B then develops accuracy with given measurements, requiring students to calculate perimeters directly.

In Section C, the focus shifts to working out missing side lengths, encouraging systematic use of properties of rectilinear shapes.

Section D consolidates these skills with more varied examples, while Section E extends thinking to problem-solving tasks where pupils must explain their reasoning, deal with incomplete information, and apply algebraic expressions in perimeter problems.

This structured progression helps students strengthen both calculation and logical reasoning, making the resource suitable for practice, consolidation, and stretch.
