Answer:
Scale = 1/200 = 1 : 200
Therefore, 1 centimeter on the plan represent 200 centimeters on the original length.
Step-by-step explanation:
Scale is the ratio of the original object to the drawn plan.
Scale = plan : original
Scale = plan length ÷ original length
Plan length = 7.5 centimeters
Original length = 1.5 meters = 1,500 centimeters
Substituting the values;
Scale = 7.5/1500 = 1/200
Scale = 1 : 200
Therefore, 1 centimeter on the plan represent 200 centimeters on the original length.
