Tv Is 40 inches in length and 24 inches in width how tall is it

Answer

TV screens are measured on the diagonal

. In this specific case the TV is shaped like a rectangle, whose diagonal is 40 i n c h e s and its width is 24 i n c h e s : w =

24 i n d = 40 i n

Then, the sides of the rectangle and its diagonal form a right triangle.

Therefore, we can determine the height (l)

if we can apply the Pythagorean theorem: d 2 = l 2 + w 2

So, solving for l : l = √ d 2 - w 2

Thus, substituting: l = √ (40) 2 - (24) 2

Simplifying: d = √ 1024 = 32 i n

Therefore

, the height of the TV is:

32 i n
