A polygon has vertices at (4, 1), (4,7), (10, 7) and (10, 1). How does the perimeter of the polygon change if each coordinate is multiplied by 3?

The perimeter goes from 24 to 72

24*3 = 72

Explanation:

I recommend plotting the four points on the same xy grid system. Connect the points with segments to form a rectangle. This rectangle is also a square. You should find that each side of the square is 6 units long, so the perimeter is 4*6 = 24 units.

If we multiply each coordinate by 3, then that will make each side length 3 times longer than before. That means each side is now 6*3 = 18 units long. The perimeter is 4*18 = 72 units.

Note how the jump from 24 to 72 is "times 3". Therefore, the scale factor of 3 will make the new perimeter 3 times longer compared to the old perimeter.

15 batches are the most you can make
