This came from a friend of mine who has a math book on hand with a statement that doesn't seem to make sense. Neither of us are in school/college at the moment. This is math for the fun of it.
I've thought long and hard on this and even, at one point, ran into a reference to a barn and 100 feet of fence to section off a rectangular plot using the side of the barn.
I tested out A(x) = xh by itself and substituted h by making it relative to x (x/2 = h or that is to say that the height is 1/2 the width). When looked at it that way, the output for A(x) makes sense for the area. I cannot make sense of the 2 though in A(x) = 2xh.
So the question of the hour is as stated above.
Where did the 2 come from?
The area of the rectangular plot is the product of it's length (h) and width (x). We can write the area as a function of x: A(x)=2xh
