janet worked on a garden shaped like a triangle with a base that is 5 m less than twice the height. If the area of the garden is 90 m^2, how long is the base and the height?

  • pre calculus -

    90 = 1/2 (2h-5) h
    h = (5+√1465)/4
    b = 2h-5 = 1/2 (√1465 - 5)

    odd answer, so better check my math
