On the above problem we stopped the calculation with only 2 decimal places being determined. That is not the COMPLETE answer. It is only accurate to 2 decimal places. Often in school you may be asked to give such an answer instead of the COMPLETE answer. Why would this be? Most often it is because to get the COMPLETE answer may take lots of time and, sometimes, the method you use is just as important as getting the COMPLETE answer. We could have continued the above steps until we got the entire solution which is: 545.439272513449.
