Answer:
Option D
Explanation:
Since the given triangle is a right angle triangle and it has been given that squares 1, 2 and 3 are constructed on its respective sides.
Since the triangle is the right angle triangle so it will follow Pythagoras theorem.
Hypotenuse² = (height )² + (base)²
since hypotenuse is the one side of square 3
so area of square 3 = Hypotenuse²
similarly height² = area of square 1
Base² = area of square 2
so area of 1 + area of 2 = area of 3 will be defined by the Pythagoras theorem.
Therefore, Option D. is the answer.
