Question

The floor of a rectangular living room is 12 meters by 9 meters. what is the distance between opposite corners of the living room? (This is pythagorean theorem btw)​

Answer 1

15 meters

Explanation:

that means the leg lengths of the triangle are 12 m and 9 m

use Pythagorean theorem:

D = root (12^2 + 9^2) = root( 144 + 81) = root(225) = 15 m
