Question

At a particular time of a day,a 7m high pole cast a shadow which is 8.2m long what is the height of the building which cast a shadow 20.5 meters in length at a same moment

Answer 1

Answer:

Height of the flagstaff that casts a shadow of length 8.2 m = 7 m

Height of the building that casts a shadow of length 1 m = m

Height of the building that casts a shadow of length 20.5 m = m = 17.5 m

∴ The height of the required building is 17.5 m.
