    Apply pythagorean theorem.

    c^2 = a^2 + b^2

    a^2 = c^2 - b^2

    a = √(c^2 - b^2)

    a = √[(6.5)^2 - (2.5)^2] = √(36) = 6

    solving the perimeter of the right- angles triangle..

    P = a + b + c

    P = 6.5 cm + 6 cm + 2.5 cm = 15 cm answer//

    A right-angled triangle

    with a hypotenuse of 6.5 cm and another side of 2.5 cm:

    x^2 = 6.5^2 - 2.5^2

    x = sqrt (9*4) = 6

    The perimeter = 15 cm

    Using Pythagoras the 3rd side is 6cm and so the perimeter is 6.5+2.5+6 = 15cm

    -

    x² = 6•5² - 2•5²

    x² = 4 x 9

    x = 6 cm

    P = 6 + 6•5 + 2•5 cm

    P = 15 cm
