Hello I have this word problem that I am having problems solving. Hopefully someone can help
Here is it.
A piece of wire 10m long is cut into two pieces. On piece, of length x, is bent into the shape of a square. The other is bent into the shape of a equilateral triangle.
(a) expess the total area of a enclosed as a function of x
b. For what value is of x is this total area a minimum.
This is what I think I can figure out.
One side of the square is s = x/4
One side of the triangle is s = (10 -x)/3
Area of Square is A= lw
Area of Triangle is A = 1/2bh
How do I go from here.
TIA
I may be totally wrong
