Answer:
Area of polygon = 16.11 square cm
Explanation:
From the figure we can divide the polygon into two quadrilateral,
1) a square with side 3.6 cm
2) a rectangle with dimensions 2.1 x 1.5
To find the area of square
Area = side x side = 3.6 x 3.6
= 12 .96 square cm
To find the area of rectangle
Area = Length x Breadth
= 2.1 x 1.5 = 3.15 square cm
Area of polygon
Area = 12.96 + 3.15 = 16.11 square cm
