If you used a scale factor of 2/3

and had a rectangle with a length of 6 cm, what would be the length of the resulting rectangle after dilation?
explain why its 4

If the scale factor used is 2/3, that means the resulting length of the rectangle after dilation would be 2/3 times the original length.

If the original length of the rectangle is 6 cm, then the resulting length after dilation would be:
(2/3) * 6 = 4 cm

This is because multiplying 6 cm by 2/3 is equivalent to dividing 6 by 3 and then multiplying by 2, which results in a length of 4 cm.
