Answer 1

`\approx 6.75 ft`

Explanation:

First let's set up a ratio...

Ferris Wheel Height : Ferris Wheel Shadow = 212:110

Man's Height : Man's Shadow = x:3.5

We can rewrite the ratios as fractions:

`(212)/(110) =(x)/(3.5)`

Now, we can solve using cross multiplication (multiply the numerator of the first fraction with the denominator of the second fraction, and the numerator of the second fraction with the denominator of the first fraction)

742=110x

Divide both sides by 110 to isolate x

`x\approx6.75` ft
