Answer:
When dealing with area (2 dimensions) when we deal with a one dimensional quantity (distance) it changes a 2 dimensional quantity by the square of the difference.
Comparing a 3, 4, 5 triangle to a 6, 8, 10 triangle, the larger triangle has 4 times the area of the smaller triangle.
20) 6 / 4 = 1.5 1.5 ^2 = 2.25
Therefore, ABC's area is 2.25 larger than A'B'C's area.
21) 21 / 7 = 3 and 3^3 = 9
Therefore, ABC's area is 9 times larger than A'B'C's area.
