it is simply area of the trapezoid - area of the semi circle. 

Trapezoid 

$$A = \frac{1}{2} \times (a + b) \times height$$

a and b are the parallel sides  8 and 14, the height = 5

the semi-circle is 

$$A = \frac{\pi \times r^2}{2}$$

you are given a diameter of 8 so find the radius

campbell_st · Answer

you have a = 8, b = 14 and height = 5

just substitute them into the formula to calculate the area
