If a two-dimensional shape is dilated by a factor of 13 , what is the effect on the area?
a. It is 1/3 as great.
b. It is 1/6 as great.
c. It is 1/9 as great.
d. It is 2/3 as great.
If a two-dimensional shape is dilated by a factor of 13, the area will be increased by a factor of 13^2 = 169. Therefore, the correct answer is:
d. It is 2/3 as great.
