A tv has a screen that is 15 in long and has a 25 in long diagonal find the area of the tv screen?

300 in²

Step-by-step explanation:

The TV screen is rectangular in shape.

Thus:

Length of the rectangular screen = 15 in.

Diagonal of the rectangular screen = 25 in.

To find the area of the rectangular screen, we need the length and the width of the screen.

Use pythagorean theorem to find the width as shown below:

, where:

a = width = ?

b = 15 in.

c = 25 in. (The hypotenuse/longest side)

Plug in the values into the equation

Subtract 225 from each side

Take the square root of both sides

width of the screen = 20 in.

Thus,

Area of the screen = length × width

= 15 × 20

Area = 300 in²

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
