Question 751826: the perimeter of a square is thrice the perimeter of a rectangle. if the perimeter of the square is 84 cm and the length of the rectangle is 8 cm, what is the difference between the breadth of the rectangle and side of the square? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! The side of the square = 84/4 = 21cm
The perimeter of the rectangle = 84/3 = 28cm
Perimeter = 2 lengths + 2 breadths
2 lengths + 2 breadths = 28 cm
2 x 8 cm + 2 breadths = 28 cm
2 breadths = 28 cm - 16
breadth = 6 cm
Therefore difference between the breadth of the
rectangle and the side of the square is:
21cms - 6cms = 15 cms
