Perimeter and Area


  1.  The perimeter of a shape is the distance around the outside of it – it would be measured in distance such as millimetres, centimetres, metres or kilometres.
  1.  The easiest way to find perimeter is to choose a point, then travel around the shape adding on the lengths of each side.

Example 1:

perameter-and-area-example1

If we start from the corner marked with an X and move  clockwise, this would be the sum –    11+6.5+8+4 = 29.5cm

 

3.  The area of a shape is the amount of space covered inside the shape. It can be measured in units such as mm2 , cm2

4.  The area of a rectangle is found by multiplying the length by the width.

Example 2:

perameter-and-area-example2

We can find the area of the shape by multiplying the length, 7cm, by the width, 5cm.

7 x 5 = 35 therefore, the area is 35cm 2
