What is the shape of the parking lot mentioned in the problem?

• Rectangle

• Parallelogram

• Circle

• Triangle

What is the length of the parking lot in the real world?

• 150 meters

• 300 meters

• 5 centimeters

• 10 centimeters

What is the width of the scale drawing of the parking lot?

• 5 centimeters

• 10 centimeters

• 300 meters

• 150 meters

How do you express the scale ratio of the lengths in the problem?

• 5 centimeters to 150 meters

• 10 centimeters to 300 meters

• 10 centimeters to 150 meters

• 5 centimeters to 300 meters

What is the first step in simplifying the scale ratio?

• Divide both sides by 10

• Multiply both sides by 10

• Add 10 to both sides

• Subtract 10 from both sides

What is the simplified scale ratio for the length?

• 1 centimeter to 60 meters

• 1 centimeter to 50 meters

• 1 centimeter to 30 meters

• 1 centimeter to 15 meters

What is the scale ratio of the width before simplification?

• 5 centimeters to 150 meters

• 10 centimeters to 300 meters

• 10 centimeters to 150 meters

• 5 centimeters to 300 meters

What operation is performed to simplify the width's scale ratio?

• Multiply both sides by 5

• Divide both sides by 5

• Subtract 5 from both sides

• Add 5 to both sides

What is the simplified scale ratio for the width?

• 1 centimeter to 15 meters

• 1 centimeter to 60 meters

• 1 centimeter to 30 meters

• 1 centimeter to 50 meters

What is the final answer choice for the scale ratio?

• Answer D

• Answer C

• Answer B

• Answer A
