Hi, 

 width of the rectangle is 4 centimeters less than its length

Let x and (x-4) represent length and width respectively

Question states***

x(x-4)= 96 in^2

 x^2 - 4x - 96 = 0

 (x-12)(x+8) = 0

    x = 12, throwing out negative solution for unit measure

 Length is 12cm and width is 8cm

   12in*8in = 96cm^2
