The only "simplify" answer would be in a decimal other than that 2 is not divisible into 45. If you can't fine a whole number that multiplied with the numerator gives you the exact number of the denominator that means that you would have to use decimals or radicals.
First you need to find the area, the formula is A=LxW, multiply 14 by 11, that’s the area. If one back covers 22 ft we need to find how many 22s are in 154, to do that you divide. Make sense?
