17. When finding the area of a polygon, which of the following statements is TRUE?
A.You can only find the polygon's area if the polygon is a triangle, rectangle, or square.

B.You can only find the polygon's area If the polygon is regular.

C.You can find the polygon's area by dividing it into triangle and rectangle sub-parts, as long as the sub-parts cover the polygon with no space and no overlap.

D.You can find the polygon's area by dividing it into triangle and rectangle sub-parts, and those subparts can contain gaps and overlaps.

Answer: You can find the polygon’s area by dividing it into triangle and rectangle sub-parts, as long as the sub-parts cover the polygon with no space and no overlap.

Step-by-step explanation;

Option A is wrong since you can find a polygon's area even if the polygon is not a triangle, rectangle, or square.
Option B is wrong since you can find the polygon's area even if the polygon is not regular.
Option D is wrong since you can find the polygon's area by dividing it into triangle and rectangle sub-parts, but those subparts cannot contain gaps and overlaps.
This only leaves us with the correct option: Option C.
