Answer:
We will split the trapezoid into right angle triangle and rectangle
Traingle with base 3cm and height 10 - 6 = 4cm
Area of traingle
= ![\frac{1}{2}*base *height = \frac{1}{2} * 3 * 4 = 6cm^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2Abase%20%2Aheight%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%203%20%2A%204%20%3D%206cm%5E%7B2%7D)
Area of rectangle with sides 6cm and 3cm
=
Therefore, area of the trapezoid
=
Area of the semi circle with radius 3/2 = 1.5cm
= ![\frac{1}{2}\pi r^{2} = \frac{1*\pi *1.5*1.5}{2} = 1.125\pi cm^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Cpi%20r%5E%7B2%7D%20%20%3D%20%5Cfrac%7B1%2A%5Cpi%20%2A1.5%2A1.5%7D%7B2%7D%20%3D%201.125%5Cpi%20cm%5E%7B2%7D)
![Total area = 24 + 1.125\pi =27.53cm^{2}](https://tex.z-dn.net/?f=Total%20area%20%3D%2024%20%2B%201.125%5Cpi%20%3D27.53cm%5E%7B2%7D)
