According to the data given above,
AB = 20 cm
BC = 12 cm
AF:FE = 3:2 
now,
let AF = 3x and FE = 2x
and ED = x
therefore,
AF + FE + ED = AD
and AD = BC = 12 cm 
since opposite sides of a rectangle is equal.
therefore,
3x + 2x + x = 12
5x + x = 12
6x = 12 
x = 12 / 6
x = 2
therefore value of FE =2x = 2 * 2 = 4
therefore FE = 4 cm
