<PRE><B>Question 106170</B>
the height of a triangle is five feet less than two times the base. If the area is 75 square feet find the base and height.
---------------
Formula: Area = (1/2)(base)(height)
75 = (1/2)(x)(2x-5)
150 = x(2x-5)
2x^2-5x-150 = 0
(2x+15) (x-10)= 0
x=-15/2 ; x=10
Only x=10 is realistic (base = 10 ft.)
Then height = 2*10-5 = 15 ft.
