Is this correct and if not how do I solve quick

Step-by-step explanation:

since the area of the square is 441 we know each side measure is which is 21

since this is a right triangle and we know the value of two sides we can use the Pythagorean Theorem to find the third side, in this case the 'hypotenuse'

theorem states that the sum of the legs, squared, equals the hypotenuse squared

20² + 21² = x²

400 + 441 = x²

x² = 841

x = which is 29
