This is our final lesson of calculating perimeter.
Look at the in focus question below. How are we going to calculate the perimeter?
Look at the Q1 as this shows the diagrams with the measurements.
If we add all the measurements of the outside of the shape, we have 22cm which is the perimeter.
Now look carefully at the next page which shows the same diagram but without measurements.
Have a go at the guided practice section below.
Now complete worksheet 4 in workbook 5B. If you are working from home, complete the activity on Seesaw.
