Answer:
6×11=66 cm. for the rectangle(length × width) and for the circle the equation is a= π5.5² (to get 5.5 just divide it 11 by 2 because there is no equation for the diameter in area so you have to get the radius):
a=π5.5²
a=π30.25
a=94.985 cm.
Since this is a semi-circle and not a full circle you divide 94.985 by 2 to get 47.4925 cm. Then combine the area of rectangle(66 cm.) and the area of the semi-circle(47.4925 cm.) (add them up) to get the answer:
113.4925 cm.² (remember to add the cubic units since it's area).
