Question

find area of polygons​

Answer 1

Answer:

Step-by-step explanation:To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.May 10, 2019

Answer 2

Step-by-step explanation:

Area of polygon= Area of (tri.EFD + tri.DFC + tri.BCF + tri.ABF)

Area of a tri. =1/2 base × height

Area of polygon=1/2 2×5 + 1/2 4×7 +1/2 4×7 + 1/2 2×6.5

=5 +14+14+6.5

=39.5 cm^2
