Sujith intends to draw a parallelogram of particular area, so he choose to draw it with base length \(11\) \(cm\) and height \(5\) \(cm\). Accidentally, its dimensions are increased by \(3\) \(cm\) and \(5\) \(cm\) respectively, then answer the following.
1. Find the required area of the parallelogram in \(cm^{2}\).
2. Express the new area of the parallelogram in terms of \(a\),\(b\), \(m\) and \(n\).
3. What is the new area of the parallelogram in \(cm^{2}\), using the distributive property?
4. Find the increase in area of the parallelogram in \(cm^{2}\), using the distributive property?
