<pre>
Diagonal divide the rectangle in two triangles, each of which is (3-4-5) right angled triangle.


Therefore, the dimensions of each triangle are 3x, 4x and 5x inches, where x is their common measure, now unknown.


We will find x very easy by noticing that 5x = 55 inches;  hence  x = 11 inches.


Therefore, the dimensions of the TV are  3*11 = 33 inches and  4*11 = 44 inches.    <U>ANSWER</U>
