Given:
The figure of a polygon.
To find:
The area of the polygon.
Solution:
Area of a triangle is
Area of trapezoid is
Where, a, b are bases and h is the height.
The area of the triangle with base 6 cm and height 8 cm is
Height of the trapezoid is
and the bases are 6 cm, 12 cm. So, the area of the trapezoid is
Now, the total area of the polygon is
Therefore, the area of the polygon is 69 sq. cm.
