High-definition (HD) televisions today have a 16:9 aspect ratio (width to height). The advertised screen size is equal to the screen diagonal.

Allowing for 2 inches of Styrofoam padding on all sides of the TV, what is the smallest possible length and width of a shipping box for a 75-inch HD TV?

With screen width 16x and height 9x, you have
(16x)^2 + (9x)^2 = 75^2
So add 4 in to both width and height
