This is the question:
A strand of wire of length 32cm is cut into two pieces. One piece is bent to form a rectangle of width x cm and length (x + 2) cm, and the other piece is bent to form a square.
A) show that the square has sides of length (7 - x) cm.
B) given that the total of the areas enclosed by both the rectangle and the square is 31cm2., form an equation for x and solve t to find the value of x.
I can for example work out that:
x^2 + 2x + 32-(x^2 + 2x)=32
But the x's all cancel each other out so can't work out how to get x?
Can someone give me a helping hand please?
