                Area of a Triangle. The area in square meters of a triangle is given by A(x)=x^2+5x+6
a)Find A(5)
b)If the length of the triangle is x+3 then what is the base of the triangle?

    a(5)=5^2+5*5+6
compute that.
Now, Area is also equal to 1/2 base*length
but when x=5, length is 8, and area is as above.
Area=1/2 (8)*base
solve for base.

    Can you let me know if I went wrong here
A(5)=52+5(5)+6
5A=25+25+6
5A=56
A=56/5
    
A(5)=52+5(5)+6
5A=25+25+6
5A=56
A=56/5
