Avneet buys \(9\) square paving slabs, each with a side of \(\frac{1}{ 2}\) m. He lays them in the form of a square.
What is the perimeter of his arrangement
Shari does not like his arrangement. She gets him to lay them out like a cross. What is the perimeter of her arrangement ?
Which has greater perimeter?
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.)
(a) \(6\)\(m\) (b) \(10\)\(m\) (c) Second arrangement has greater perimeter. (d) Yes, if all the squares are arranged in row, the perimeter be \(10 \)\(cm\).
