The pyramid of Khufu in Giza, Egypt was the
world's tallest free-standing structure for more than 3,500 years. Its original height was about 144 meters. Its base is approximately a square with a side length of 231 meters. 

The diagram shows a cross section created by dilating the base using the top of the pyramid as a center of dilation. The cross section is at a height of 96 meters.

a. What scale factor was used to create the cross section? _______ 
b. What are the dimensions (length x width) of the cross section? _______ meters by _______ meters
