Well... if the side lengths are 14 and 16. The problem would be a^2 + b^2= c^2. 14 times 14 is 196. 16 times 16 is 256. If I add those together it would equal 452. So far the equation is 452= c^2. The diagonal is 452 square rooted which is 21.3 feet rounded to the nearest tenth. So the diagonal of the bed is 21.3 feet!
We're here! My room is 14 feet by 16 feet.
Let's go inside!
Hello, I would like to purchase a 14 by 16 foot mattress, but I need to know the diagonal of the mattress.
