We can see here that the area of the polygon is: D. 186 square units.
A polygon is a two-dimensional closed geometric shape made up of straight line segments connected end-to-end to form a closed figure. These line segments are called sides or edges of the polygon. The sides do not cross each other, and each side intersects exactly two other sides, except for the endpoints.
We can see here that the above answer is gotten thus:
11² + (5 × 6) + (5 × 7)
= 121 + 30 + 35
= 186 square units.
Polygons can be regular or irregular. A regular polygon has all sides of equal length and all interior angles of equal measure. Irregular polygons have sides and/or angles of different lengths or measures.
