Avneet buys $9$ square paving slabs, each with a side of $\frac{1}{2} \mathrm{m}$. He lays them in the form of a square.

What is the perimeter of his arrangement ?

 Which has a greater perimeter?

Avneet buys $9$ square paving slabs, each with a side of $\frac{1}{2} \mathrm{m}.$ He lays them in the form of a square.

Avneet wonders if there is a way of getting an even greater perimeter. Can you find a way of doing this? (The paving slabs must meet along complete edges i.e. they cannot be broken.)
