(a) The area of this rectangle = 30 m  20 m = 600 square m.
Yes, its area is more than that of the first rectangle.

(b) Many other rectangle can be made with 100 metres of wire. For Example,
5m * 45m having area 225 square metres.
15m * 35m having area 525 square metres.
20 m * 30m having area 600 square metres.
25m * 25 m having area 625 square metres.
The rectangle having length = breadth i.e. a square will have the biggest area.
