What is the area of a 29" traditional TV screen

Question

Althe screen size of a television is determined by the length of the diagonal of the rectangular screen traditional TV's come in a 4: 3 format meaning the ratio of the length to with of the scream is the 4 to 3

Answer 1

The length, width and diagonal form a 3:4:5 right triangle. (Use the Pythagorean Theorem to see how this works-------5² = 4² + 3² )

So the width is 4/5 * 29 = 23.2

length is 3/5 * 29 = 17.4

CHECK:

23.2² + 17.4² = 538.24 + 302.76 = 841

29² = 841
