To solve this problem, we need to understand how the areas of similar figures are related given a scale factor.

Let the side length of pentagon PQRST be [tex]\( s \)[/tex]. Therefore, the side length of pentagon ABCDE is [tex]\( 6s \)[/tex] (since it's given that ABCDE is 6 times the side length of PQRST).

Given that the shapes are similar, the ratio of their areas is proportional to the square of the scale factor of their corresponding side lengths.

Here, the scale factor is 6. So to find the area ratio, we square the scale factor:
[tex]\[ \text{Area ratio} = 6^2 = 36 \][/tex]

Thus, the area of pentagon ABCDE is 36 times the area of pentagon PQRST.

From the given statements, the correct answer is:
C. The area of pentagon ABCDE is 36 times the area of pentagon PQRST.
