A tall building casts a shadow of 20 meters. John, who is 1.5 meters tall, casts a shadow of 10 cm. how tall is the building?
Answered by Steve
h/20 = 1.5/0.1
Answered by John
150 cm /10 cm = x/2000 cm

cross multiply to get x


10x = (150)(2000)
divide by 10 to find answer in cm.

change to meters by dividing by 100.
