​

Answer 1

Answer:

Step-by-step explanation:

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 = 78.278.2 m                                          

Height of the building that casts a shadow of length 20.5 m = 78.2×20.578.2×20.5 m = 17.5 m

∴ The height of the required building is 17.5 m.
