Kathleen made a scale drawing of a house and its lot. The scale she used was 2 millimeters = 1 meter. The front patio is 11 meters wide in real life. How wide is the patio in the drawing?

The given scale is

2 mm = 1 m

multiply both sides by 11 to turn the "1 m" into "11 m"

so we get

11 * (2 mm) = 11 * (1 m)

(11*2) mm = (11*1) m

22 mm = 11 m

This means that 11 meters in real life corresponds to 22 millimeters on the page

Answer: 22 mm
