The total area of the canvas and the new frame is given by the polynomial , where h represents the height of the canvas. Determine the width of the new frame. Show all your work. Explain why you did each step. (2 points)

1. A= width*height=h ^2 = (3)^2 = 9 
2. A=width*height 
height is still gonna be h 
Area is given in the problem 
h^2+8h+12=(width)h 
So doing some long division.. 
h√h^2+8h+12 = h+8+12/h 
-(h^2) 
8h+12 
-(8h) 
12 

3. A=width*height=h(h+4)=h^2+4h
