Question 202532: The area of a square meters for a trianglar sail is given by A(x) = x^+5x+6
a) Find A(5)
b) If the height of the sail is x+3 meters, then what is the length of the base of the sail?
I was able to factor out the equation which is (x+3) (X+2). I'm not sure how to answer a + b. Can you help me out by providing an example that I can follow?

If :
1) Find Substitute x = 5 into the given equation for the area.
Evaluate.

sq.meters.
2) Use the formula for the area of a triangle:
Substitute: ,
Multiply both sides by 2.
Factor the left side.
Divide both sides by (x+3)
Cancel the common factors.
