The area of polygon is 18 sq. units.
In geometry, a polygon is any closed curve made up of a collection of continuous line segments, without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons.
Given that jack has a model f(x) = x² + 2x +3
where f(x) is area of polygon and x shows length of side
area when length is 3
substitute value of x in equation
f(x) = x² + 2x +3
f(3) = 3² + 2ₓ3 + 3
f(3) = 9 + 6+ 3
f(3) = 18
Hence area of polygon according to given equation is 18 sq. units
