The height of a triangle is 5cm more than the length of the base .if the area of the triangle is 75cm2, find the height and length of the base
----------------
Area = (1/2)(height)(base)
------------------------
75 = (1/2)(x+5)(x)
------
150 = x^2 + 5x
-------
x^2 + 5x - 150 = 0
Factor::
(x+15)(x-10) = 0
Positive solution::
base:: x = 10 cm
------
height:: x+5 = 15 cm
--------------------------
