Find the perimeter and area of a right triangle if the shortest side is 16 in. and the longest side is 34 in. Include correct units with each part of your solution.

  • math - ,

    First, find the length of the third side by using the Pythagorean Theorem.

    a^2 + b^2 = c^2

    16^2 + b^2 = 34^2
    256 + b^2 = 1,156
    b^2 = 1,156 - 256
    b^2 = 900
    b = 30 inches

    The perimeter is the length of all three sides added together.

    The area is found with this formula:
    A = bh/2

    If you post your answers here, I'll check them for you.

    the longest side in a right-angled triangle is the hypotenuse, let the missing side be x

    x^2 + 16^2 = 34^2
    x^2 = 900
    x = 30

    perimeter = sum of the three sides
    area = (1/2)(16)(30) = ....

    Should have checked first.
