A rectangular glass coffee table is designed with a transparent glass top and a wooden border. The glass portion has a length and width in the ratio of \(5: 3\). The wooden border around the glass add \(7\) \(inches\) to the total width and \(14\) \(inches\) to the total length. Let the length of the glass portion be \(5x\) \(inches\).
Based on this, answer the following:
1. What is the total length of the coffee table(including the wooden border) in terms of \(x\)?
2. What is the total width of the coffee table(including the wooden border) in terms of \(x\)?
3. What is the polynomial expression representing the total area of the coffee table(including the wooden border)?
4. What are the zeroes of the polynomial representing the total area?
