Question 733683
we use right triangle ratios to solve this problem:

The ratio (note that Tony's height in inches is 48) for Tony's house height is

48/9.6 = x/62.4, cross multiply fractions, 9.6x = 2995.2, x=312 inches or 26 feet in height

The ratio (note that Dermont's height in inches is 60) for Dermont' house is

60/15.6 = y/62.4, cross multiply fractions, 15.6y = 3744, y=240 inches or 20 feet in height

Therefore Tony's house is taller
