Perimeter and areaSituations involving perimeter

Enclosures could be any three of \(9m \times 1m\), \(8m \times 2m\), \(7m \times 3m\), \(6m \times 4m\) and \(5m \times 5m\). You may have other possibilities if you used fractions. Each enclosure must have a perimeter of \(20m\).

The enclosure which is \(5m \times 5m\). The area is \(25m^{2}\)
