Let w and 2w-6 be the width and length, respectively. Then:
w(2w-6)=176
2w²-6w-176=0
(2w+16)(w-11 )=0
w=-16/2 or 11
If the width is 11 km, then the length is 16 km

The CPI or the Customer Price Index is calculated through the equation,
CPI = (price at a certain year/ price at the base year) x 100
If our base year is 1983, the price of a year-long newspaper subscription will cost,
193 = (price at a certain year / 12.75) x 100
price at a certain year = $24.6075
Thus, the current price which is $28.50 is slightly higher than the expected price based on the given CPI.
