You would think it was 3 * 12 = 36. Not so. All polygons have to be broken down into some figure that will give 2 dimensions that are at right angles to each other. That would mean that d1 * d2 = Area for the small polygon 3d1 * 3d2 = area of the larger polygon
What that means is that the area of the larger one is 9 times the smaller one. Area large = 12 * 9 = 108 square units. <<<<< answer.
If you find this hard to be leave try it with a square. Suppose you have a square (the small one) that is 3 cm by 3 cm The small one has an area of 3*3 cm^2 = 9 cm
Now you have another square that is 3 times larger. That means that each side is 3*3 = 9 So s = 9 Area = s^2 Area = 9^2 = 81 cm^2 81 is 9 times larger than 9 just as you would think.
sustitue -4 into x for 3-x which would equal 7 because a negative times a negative equals positive. Then substitue 1 in for x in -4x-5 which would get you -9
