    Question

    In a right-angled triangle, the perimeter is 60 cm. If

    the base is 12 cm and the height is 16 cm, find the length of the hypotenuse.
    A 18 cm Correct Answer Incorrect Answer
    B 20 cm Correct Answer Incorrect Answer
    C 22 cm Correct Answer Incorrect Answer
    D 24 cm Correct Answer Incorrect Answer

    Solution

    Let the hypotenuse be c. Given: Perimeter = 60 cm, base = 12 cm, height = 16 cm. We know that the perimeter of a triangle is the sum of all sides: 12 + 16 + c = 60, so c = 60 - 28 = 32 cm. Using Pythagoras' theorem: c² = 12² + 16² c² = 144 + 256 = 400 c = √400 = 20 cm. Correct option: B) 20 cm
