Question 524722: The length of the base of a triangle is six times its height. If the area of the triangle is 75 square kilometers. find the height (A = 1/2 b h)
I got the height = X
and the base 6x
every time i plug it in i am getting 75 = 1/2 (6x)(x)
75 = (3x)(x2) then 0 = x2 +3x-75 and now i am stuck on (x+ )(x- ) can you please tell me where i am messing up thank you

height =x
base = 6x
Area = 1/2 * base * height
Area = 1/2 * x*6x
3x^2= 75
/3
x^2=25
x=5 km the height
Base = 30 km
