What is the perimeter of a computer graphic with sides measuring:

2 times the square root of 50, 3 times the square of 72, 6 times the square root of 98, and 3 times the square root of 12 centimeters?

  • Algebra -

    just add up the sides:

    2√50 + 3√72 + 6√98 + 3√12
    factor out perfect squares:
    2*5√2 + 3*6√2 + 6*7√2 + 3*2√3
    70√2 + 6√3
