The ratio of the length and the width of a rectangle is 4 : 3 and the area of the rectangle is 5292 sq cm. What is the ratio of the width and the area of the rectangle?  Choose the correct option
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) = 5292   12x^2 = 5292   x^2 = 441   x = 21   The ratio of the width and the area is 3x : 12x^2 = 1 : 4x = 1 : 84   The answer is 1:84.
