The width of a business card is 4 centimeters shorter than the length. The area of the card is 45 square centimeters. Determine the perimeter of the card
The factors of 45 are: 1,3,5,9,15, and 45. 5 is 4 less than 9 so 5 is your width and 9 is your length. P= (2x9)=18 and (2x5)=10. 18 plus 10 equals 28. Hope this helps!
