Answer:
Area of polygon = 16.11 square cm
Step-by-step 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
<u>To find the area of square</u>
Area = side x side = 3.6 x 3.6
= 12 .96 square cm
<u>To find the area of rectangle</u>
Area = Length x Breadth
= 2.1 x 1.5 = 3.15 square cm
<u>Area of polygon</u>
Area = 12.96 + 3.15 = 16.11 square cm
