TV width

The electronics store offers a TV with a diagonal screen of 33 inches; the screen's height (without borders) is 44 cm. How wide is the TV if the edge on each side of the screen is 1.1 cm?

Final Answer:

x =  73.54 cm

Step-by-step explanation:

$$\begin{gathered} d=33\text{in}\to \text{cm}=33\cdot 2.54\text{cm}=83.82\text{cm} \\ a=44\text{cm} \\ o=1.1\text{cm} \\ x=\sqrt{d^2-a^2}+2\cdot o=\sqrt{83.82^2-44^2}+2\cdot 1.1=73.54\text{cm} \end{gathered}$$
