Percentages - Percentage Increase and Decrease

Every year, the value of a car depreciates by \(11\%\) of the previous year's value. Given that the value of a car is \(\$158\,000\) now, find the value of the car \(2\) years ago, giving your answer to the nearest dollar.

The breadth of a rectangle is \(x\text{ cm}\) and the length of the same rectangle is \(5\) times that of its breadth. If the length is decreased by \(40\%\) and the breadth is increased by \(35\%\), determine the percentage decrease of its perimeter.
