Answer:  
Step-by-step explanation:
In the given figure, We have a trapezoid and a triangle sharing a common base of 14 cm.
For trapezoid, 
Area = , where a and b are the opposite parallel sides and h is the height.
, where a and b are the opposite parallel sides and h is the height.
Therefore, Area of trapezoid = 
For triangle, 
The height of triangle H =18 cm - 10 cm = 8 cm
Area = , where  b is the base and h is the height.
, where  b is the base and h is the height.
Area of triangle= 
Total area of the figure =
