The perimeters are 4 cm, 6 cm, 8 cm, 10 cm and 12 cm respectively. When the side increases by 0.5 cm, the perimeter increases by 2 cm each time. This shows a linear pattern.
Find the perimeter of squares with sides 1 cm, 1.5 cm, 2 cm, 2.5 cm and 3 cm. What will happen to the perimeters if the sides increase by 0.5 cm?

The perimeter of a square is found by multiplying the side by 4. Therefore, for sides 1 cm, 1.5 cm, 2 cm, 2.5 cm and 3 cm, the perimeters are 4 cm, 6 cm, 8 cm, 10 cm and 12 cm respectively. We observe that every time the side increases by 0.5 cm, the perimeter increases by 2 cm. This increase is constant, so the pattern formed is called a linear pattern.
