A flagpole casts a shadow that is 26 ft long. At the same time, a yardstick casts a shadow that is 4 ft long. How tall is the flagpole?

Answer 1

1 yard = 3 feet

the ratio is : actual length / shadow length

3/4 = x/26

3*26 = 4*x

78 = 4*x

78/4 = x

39/2 = x

x = 19.5

The flagpole is 19.5 feet tall or 19 feet 6 inches tall
