one desk has a length of 25 inches.....a similar shaped desk has a length of 60 inches. To find the scale factor, we need to find a number, when multiplied by 25 equals 60....or u can just divide....60/25 = 2.4. So the scale factor is 2.4. So if the width of the first desk is 18, then the width of the similar desk is going to be (2.4 * 18) = 43.2 inches <=
