if a 5 foot 6 person cast a 11 foot shadow and a nearby tree casts a 20 foot shadow how tall is the tree
5 feet 6 means 5 feet and 6 inches. Change 6 inches to .5 ft (1/2 foot)
Write a proportion with the given information. There is more than one way to write this proportion. I will write it as:
person's height /person's shadow = tree's height/tree's shadow
5.5/11 = x/20 I used x for the unknown height of the tree.
Cross multiply
11x = 110 Now divide both sides by 11
x=10
