65-inch TV 132.08cm long 99.06cm wide, 75-inch TV 152.4cm long 114.4cm wide, 85-inch TV 172.72cm long 129.54cm wide.
The size of the TV, usually refers to the diagonal length of the display, the general TV display length to width ratio is: length: width =4:3. According to the meaning of the question, the equation can be listed
(4 x) 2 (3 x) =(65×2.54)2,
(4 y) 2 (3 y) 2 =(75×2.54)2,
(4 z) 2 (3 z) 2 =(85×2.54)2
Solve the equation to get x=33.02,4x=132.08,3x=99.06;
y = 38.1, 4 y = 152.4, 3 y = 114.3;
z = 43.18, 4 z = 172.72, 3 z = 129.54。
