I need help on figuring this problem out please. The height of a triangle is three feet longer than the base. The area of the triangle is 44 square feet. Find the height and base of the triangle
-----------------------
Area = (1/2)(base)*(height)
44 = (1/2)(x)(x+3)
22 = x^2+3x
---------
x^2+3x-22 = 0
-----
x = [-3 +- sqrt(9-4*-22)]/2
-----
x = [-3 +- sqrt(97)]/2
---
Positive Solution:
x = [-3+sqrt(97)]/2 (base)
---
x = [-3+sqrt(97) +6]/2
x = [3+sqrt(97)]/2 (height)
