Explanation:
Area of Rectangle at the top =
Length x Width
![= 3.5 * 3 \\ = 10.5 {mm}^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/o4cqdasujxjqpu9bcq7k9nwor5z1rz9vak.png)
Area of Quarter- Circle = 1/4 x Area of Circle
![= (1)/(4) \pi {r}^(2) \\ = (1)/(4) \pi( {3.5}^(2) ) \\ = 3 (1)/(16) \pi {mm}^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/o3ynq5qze98nhcjif53hon2a0pjxmved16.png)
Area of Rectangle at the right = Length x Width
![= 5.5 * 3.5 \\ = 19.25 {mm}^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/9o27dq19dvjrv3vae4ngi1qrp6zso0v5wx.png)
Total Area = Area of 2 Rectangles + Area of Quarter Circle
![= 10.5 + 3 (1)/(16) \pi + 19.25 \\ = 29.75 + 3 (1)/(16)\pi \\ = 32 (13)/(16)\pi {mm}^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/oionqp4bctij2trf62mydgrha3087ss3sy.png)
I will leave the answer in terms of pi as I'm not sure if you need to round off your answer.
