Arectangular us four times as long as it is wide. if the area is 144 ft^2,find the length and width of the table

x(4x) = 144 {area is width x length}
4x^2 = 144 {multiplied x by 4x}
x^2 = 36 {divided both sides by 4}
x = 6 {took square root of both sides}
4x = 24 {substituted 6, in for x, into 4x} 

width = 6ft and length = 24ft

The answer would be 27 because assuming that each package has 1 bar of soap and 1 tube of toothpaste, after 27 packages they would run out of toothpaste
