Answer:
233.5
Explanation:
1) Find the area of the rectangle
- Area of rectangle = l × w
- 12 × 11 = 132
2) Find the area of the triangle
- Area of triangle = (l × w) ÷ 2
- L = 20 - 11 = 9
- 9 × 12 = 108
- 108 ÷ 2 = 54
3) Find the area of the semicircle
- Area of semicircle = (πr²) ÷ 2
- Radius = diameter ÷ 2 = 11 ÷ 2 = 5.5
- πr² = 3.14 × 5.5² = 94.985
- 94.985 ÷ 2 = 47.4925
4) Add the results together
- 132 + 54 + 47.4925 = 233.4925
5) Round the nearest tenth
Have a lovely day :)
