Question

a building casts a shadow 48 feet long. at the same time, a 40-foot-tall flagpole casts a shadow 9.6 feet long . what is the height of the building

Answer 1

`(40)/(9.6) = (48)/(n)`

Reduce the fraction on the left by dividing by 8 (remember 8 goes into 96 so it will go into 9.6 too)


`(5)/(1.2) = (48)/(n)` Now cross multiply.

5n = 57.6 finally divide both sides by 5

n= 11.52 ft - answer
