Ayoung girl with a height of 124 centimeters casts a shadow that is 93 centimeters long. she is standing next to a tree that casts a shadow that is 13.5 meters long. how tall is the tree? ' a. 14 m b. 16 m c. 18 m d. 20 m

1. Let's convert 124 centimeters (the height of the young girl) and 93 centimeters (the length of her shadow).

2. We know that 1 meter=100 centimeters, then:

 124/100=1.24 meters
 93/100=0.93 meters

 3. If the girl has a height of 1.24 meters and casts a shadow with 0.93 meters long, what height ("x") will we obtain with a shadow of 13.50 meters long?

 1.24 m0.93 m
          x13.5 m

 x=(13.5 m)(1.24 m)/0.93 m
 x=18.0 m

 How tall is the tree? The answer is: 18.0 meters

Wait what the question
