Answer:
189.3cm2
Step-by-step explanation:
Divide the whole figure into 2 parts. One part as a rectangle and the other as a semicircle ( half a circle). First find the area of the rectangle, 10 times 15 which will get you 150cm2. Next to find the area of the semicircle do [tex]\pi[/tex] times 5 times 5 times half. You will get an amount like 39.26990817 but do not worry for now. Just keep it like that. Then add this amount with 150 and you will get an amount like 189.2699082
Then round it of to one decimal place and you will get 189.3cm2
