A painter needs to know the height of a building to estimate the amount of paint needed for the front side. When the building cast an 18 ft shadow, the 6 ft tall painter casts a 3 ft long shadow. How tall is the building?
Don't laugh at me lol...it says Jamal is 5 feet tall. One sunny morning he notices that he casts a shadow that is 2 feet long. If the school building casts a shadow that is 7 feet long at the same time, what is the height of the building?
