MY answer would be 40 Sq Inches. Here is my explanation.

The TV screens are square shaped and the diagnols are given. One square diagnol is 21 inches and the other is 19 inches.

Area of the square given the diagnols is d^2 / 2 where d is the diagnol.

The question asked is the difference in the areas = 1/2 (21^2 - 19^2) = 1/2 (21+19)(21-19) = 40.

Ans is 40.
