Rayan is 5 feet tall his shawdow is 9 feet long and the shawdow of the building os 35 feet long how tall is the building.draw two similar triangles and determine the height of the building

Question

How to do it

Answer 1

The ratio of Rayan’s height to the length of his shadow is 5:9 or 5/9, and this ratio is the same as the height of the building to the length of its shadow.

So 5/9=?/35 where ? is the height of the building. Therefore if we multiply 5/9 by 35 we get the height of the building. So 5×35/9=175/9=19 4/9 feet. 4/9 ft is 4/9×12 inches=16/3 inches (5.3in approx), or we can express the answer in feet as 19.44 ft.
