Use the Pythagorean Theorem for both of these problems. The sides of the dining room or the width and height of the space for the TV are sides a and b of a right triangle and you want to find the length of the hypotenuse, c, so:



Just plug in the numbers and do the arithmetic -- use your calculator -- and for the TV question, round DOWN to the nearest inch. If you round up, then the TV you get would be a little bit to big.
