Answer:

A= 20,58m²

Step-by-step explanation:

the side opposite to what is worth 6m is the diameter of the half circle to the left. I calculate the circumference of the circle (diameter multiplied by π), so 6 × π = 18.84

since the circumference is not whole but only half, we divide the result in half: 9.42 (the length of the half circle).

formula for the area of the rectangle: base multiplied by the height all divided by 2: (10×6)/2= 30m²

we subtract half the circumference: 30-9,42=20,58m²
