A scale model of a merry-go-round and the actual merry-go-round are similar.



a. How many times greater is the base area of the actual merry-go-round than the base area of the scale model? Explain.
The ratio of the corresponding lengths is w : 1. So, the ratio of the areas is y : 1 and the base area of the actual merry-go-round is z times greater than the base area of the scale model.

I will give you a brainliest if you answer this!!!

b. What is the base area of the actual merry-go-round in square feet?

The base area of the actual merry-go-round is x square feet.
