Question

Determine how dilation affects the area of a pentagon when the sides of the pentagon are dilated by a scale factor less than 1.(1 point)
Responses

The area decreases more rapidly than the lengths of the sides decrease.

Answer 1

The area decreases more rapidly than the lengths of the sides decrease.

Reason: If side lengths scale by factor k (0 < k < 1), area scales by k^2, and k^2 < k, so area shrinks proportionally more than the side lengths.
