Answer:
its 4 times bigger. If you add 6+4...that equals 10
its 1800 square inches
Step-by-step explanation:
I could be wrong, but I believe the base of the larger merry-go-round is 9000 inches, or 750 feet. Which means the larger merry-go-round is 20x larger than the smaller merry-go-round.
6/450 = 120/x
= 9000 In, or 750 Ft
