Ms.smith is planning her classroom. She knows she has approximately 12 linear meters of available wall space. She likes to decorate around her chalkboards but she has different sizes of trim. She draws a scale drawing of her two chalkboards as shown. Use the ruler in your reference materials to mark necessary measurements to approximate in centimeters the length and width of the chalkboards. About how much smaller in meters is the perimeter of the small chalkboard than the large chalkboard.
