This worksheet gives learners the opportunity to practise measuring lengths in millimeters and then to add those lengths to find the perimeter of a shape.

Section A gives some triangles where learners will need to measure all three sides.

Section B then gives some rectangles, giving learners the option to just measure the length and width if they wish to then go on to calculating the perimeter.

Section C then provides a mixture of quadrilaterals, pentagons and rectilinear shapes.
