The length and width of the rectangle are #25 cm and 20cm# respectively.


Let the length and width of rectangle are #5x and 4x# respectively. Hence Area #=5x*4x=500 or 20 x^2 =500 or x^2 =25 or x =+-5#
Length and width can not be negative so #x=5 :. #The length is #5x=5*5=25# cm and width is #4x=4*5=20#cm[Ans]
