The new school flag has a red border with a white rectangular centre. The edge of the white centre measures 67 cm by 45 cm. The perimeter of the red border is 368 cm. How wide is the red border?

is the interior rectangle proprotional to the outside?

If it is you can use 45cm/67cm to find out the ratio of width/lenght of the outside border.
