If we take a square with side length x and draw a diagonal, we get two isosceles right triangles.   If we focus on one such right triangle, we see that the legs have length x.   square 6-inch flat-screen television   The diagonal (hypotenuse) = 6   So, we can apply the Pythagorean Theorem to get x² + x² = 6²   Simplify: 2x² = 6²   Divide both sides by 2 to get: x² = 6²/2   Since the area of the square = x², we can see that the area of this square is 6²/2   square 5-inch flat-screen television   The diagonal (hypotenuse) = 5   So, we can apply the Pythagorean Theorem to get x² + x² = 5²   Simplify: 2x² = 5²   Divide both sides by 2 to get: x² = 5²/2   Since the area of the square = x², we can see that the area of this square is 5²/2   DIFF5.5R5.5NC5.5 IN AR5.5AS =6²/2-5²/2   = (6²- 5²)/2 = (36-25)/2 =11/2=
