What you want to do first is identify the rectangles. I spot two. Do you?

looks like they are all shaded

since they are all shaded, and since you have a square, the area is the square of the side the length of the side is \(3x+4\) so the total area is \((3x+4)^2\)

How did you get that?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
by looking across the top and adding the two lengths. one is \(3x\) the other is \(4\) so the total length is \(3x+4\)

and therefore the total area is \((3x+4)^2\)

See the book is horrible at explaining how to do this, what does this have to do with Polynomials

the other answer is the area of the large square, which is \(3x\times 3x=9x^2\) plus the area of the small square which is \(4\times 4=16\) plus the area of the two reactangles, each of which is \(3x\times 4=12x\) when you add these you get \[9x^2+12x+12x+16=9x^2+24x+16\]

they are trying to get you to see by making a square, that \[(3x+4)^2=9x^2+24x+16\]
