Question

a shadow 9 meters long is cast by a maple tree that is 12 meters tall. if a windmill close by casts a shadow 12 meters long, how tall is the windmill?
write your answer as a whole number or a decimal. do not round.
______ meters

Explanation:

Step1: Set up proportion

$\frac{\text{Tree height}}{\text{Tree shadow}} = \frac{\text{Windmill height}}{\text{Windmill shadow}}$
$\frac{12}{9} = \frac{h}{12}$

Step2: Solve for $h$

$h = \frac{12 \times 12}{9}$

Step3: Calculate final value

$h = \frac{144}{9} = 16$

Answer:

16 meters
