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

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
