[scale]=[measure in model park]/[measure in actual park]
[measure in model park]=[scale]*[measure in actual park]
scale=1.5 cm/50 m

If the distance between two trees in the park is 150 m
so
[measure in actual park]=150 m

[measure in model park]=[1.5/50]*[150]------> 4.5 cm

the answer is the option
