Today’s lesson is about finding the perimeter of rectilinear shapes.
A rectilinear shape is a shape that has straight sides and right angles. It can look like two rectangles have been joined together.
This shape looks much more complicated than a rectangle, but the method of working out the perimeter is the same. Add together the lengths of all sides to find it.
