Answer 1

Answer:

By Pythagoras theorem

let height of the room be C

Now,

$c = \sqrt{(10 \sqrt{2}) {}^{2} - 10 {}^{2} } \\ = \sqrt{200 - 100} \\ = \sqrt{100} \\ = 10$

Option (d)

Answer 2

Answer:

Step-by-step explanation:

By pathagoras theorm

Let height of room = c

Then;

c = $\sqrt{(10\sqrt{2)^{2} } -10^2}$

  = $\sqrt{100}$

  =$10$

option d is correct.
