The dimensions of a room are 20 ft by 18 ft, respectively. Find the length across the diagonal of the room.

26.91 ft

Step-by-step explanation:

Well you can do this using the Pythagorean theorem and apply this to your room, which is a rectangle.

Diagonal = √h²+w²

where: h = height and w = width

So we insert our given:

Diagonal = √ (20ft) ² + (18) ²

= √400ft² + 324ft²

= √724ft²

= 26.91ft

You can look below to see the scenario.
