Question 169864: Area of a sail. The area in square meters for a triangular sail is given by A(x) = x^2 + 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?
Can someone please help me with this problem. Thank you
You can put this solution on YOUR website! Area of a sail. The area in square meters for a triangular sail is given by A(x) = x^2 + 5x + 6.
a) Find A(5).
A(5) = 5^2 + 5*5 + 6 = 56 m^2
--------------------------------------
b) If the height of the sail is x + 3 meters, then what is
the length of the base of the sail?
Area = (1/2)base*height
A = (1/2)b*(x+3)
2A = b(x+3)
base = 2A/(x+3)
