You need to use the Pythagorean theorem for this. Take the square root of (48^2 + 36^2). This will give you the length of the diagonal.
48^2 + 36^2 = 3600
Remember we need to take the square root of 3600, which is just 60.
The length of the diagonal is 60 inches.
48^2 + 36^2 = 3600
Remember we need to take the square root of 3600, which is just 60.
The length of the diagonal is 60 inches.
Answer:
Size of television screen is:
60 inches
Step-by-step explanation:
The Television screen is in the shape of a rectangle.
The size of diagonal in a rectangle is given by
[tex]diagonal=\sqrt{Length^2+Width^2}[/tex]
Here we are given
Length=48 inches
and Width=36 inches
[tex]diagonal=\sqrt{48^2+36^2}[/tex]
[tex]diagonal=\sqrt{2304+1296}\\ \\diagonal=\sqrt{3600}\\ \\diagonal=60[/tex]
Hence, size of television screen=Length of its diagonal
= 60 inches
