Answer 1

Answer:

17.5 m

Step-by-step explanation:

Given:

7 m high flagstaff casts a shadow which is 8.2 m long.

Shadow of length 8.2 m = 7 m high.

Shadow of length 1 m = (7/8.2) m high.

Then,

Shadow of length 20.5 m = (7 * 20.5)/8.2

                                           = 17.5 m high.

Therefore, The height of building is 17.5 m high.

Hope it helps!
