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.

the answer is d
