Answer:
149.3
Explanation:
Since 5 is the radius, the diameter is 10, or the radius times two. Since it's attached to the rectangle, it also means that it's the rectangle's width. now you can find out the rectangle's area, as you have the length and width.
11 x 10 = 110
Now for the circle, it's the radius squared times pi.
25
Since it's a semicircle, we should divide it by two.
25
/2
110 + 25
/2 ≈ 149.2699...
Rounded to the nearest tenth gives:
149.3
