The ratio of the length and the width of a rectangle is 4 : 3 and the area of the rectangle is 4332 sq cm. What is the ratio of the width and the area of the rectangle?
Choose the correct choice from the following answers.
A) 1:72  B) 1:76  C) 1:80  D) 1:84  E) 1:88
Let the length and the width be 4x and 3x respectively.   Area = (4x)(3x) = 4332   12x^2 = 4332   x^2 = 361   x = 19   The ratio of the width and the area is 3x : 12x^2 = 1 : 4x = 1 : 76   The answer is 1:76.
