Help ASAP please ! Explain too!

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.

Step-by-step explanation:

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i
