Finding the perimeter of rectilinear shapes can be difficult for learners particularly when there are missing lengths to calculate. This worksheet focuses on finding missing lengths in rectilinear shapes and will ensure your learners have mastered this skill.
Each question is designed to build on the last, with shapes in different orientations, dimensions of lengths given that are not needed by the pupils, addition, subtraction and even division is used to calculate missing lengths.
All shapes are drawn on a blank background, the lengths students must find are all clearly highlighted and all lengths are measured in cm.
