What is the scale factor from park ABCD to model MNOP?

• 2/3

• 3/2

• 2

• 3

Answer explanation

The scale factor from ABCD to MNOP is determined by comparing corresponding side lengths. If the sides of ABCD are 2 units and those of MNOP are 3 units, the scale factor is 2/3, indicating a reduction.
