# Widescreen monitor

Computer business hit by a wave of widescreen monitors and televisions. Calculate the area of ​​the LCD monitor with a diagonal size 20 inches at ratio 4:3 and then 16:9 aspect ratio.

Is buying widescreen monitors with same diagonal more advantageous than buying 4:3 monitor?

Result

S1 =  1238.707 cm2
S2 =  1102.707 cm2
