Jenifers flower bed is in the shape of a right angle triangle. The shortest side is one/forth of the second shortest side. if the area is 18sqaured what are the lengths of ALL THREE SIDES?

I NEED A ANSWER ASAP! PLEASE

  • math - ,

    short side --- x
    longer side ---- 4x

    area = (1/2) base x height

    (1/2)(x)(4x) = 18
    2x^2 = 18
    x^2 = 9
    x = √9 = 3

    short side = 3, longer side = 12
    let the hypotenuse be h
    h^2 = 3^2 + 12^2 = 153
    h = √153 or appr 12.37
