considering th standard one first:

given that the width is 4/3 of the height

height, h = h

width, w =

also given that that size of the TV is 28 inches(71.12 cm), this is actually the hypotenuse of the TV

Area of the screen

= area of a rectangle with a diagonal of 28 inches

do the same thing for the widescreen TV and i get 335.003 inches^2. Hence concluding that the standard picture TV has a larger area.
