I can't seem to figure out this word problem that involves factoring. Here is the question and what I have so far:
"The side of a square equals the width of a rectangle. The length of the rectangle is 6cm longer than its width. The sum of the areas is 176cm^2. Find the length of the side of the square."
I'm not sure whether there are two separate equations in this equation.
s = side of square
w = width of rectangle
area of square = (w)(length)
w = s
length of rectangle = ( w + 6)
area of rectangle = w(w+6)
I've tried pull all in a single equation which isn't. Any advice on how to solve this?
