Answer: 33.34
Step-by-step explanation: first we have to cut this shape up like you would a pizza
2 triangles and 1 rectangle, we know that the rectangle is 10 by 3 cm, but we don't have all the measurements for the triangle.
Find the last side using this equation:
3.2 squared = 10.24
3 squared = 9
subtract
1.24
square root of 1.24 = 1.11
Area of rectangle:
10 x 3 = 30
Area of triangle:
1.11 x 3 ≈ 1.67
Final Area:
30 + 1.67x2 = 33.34
