Answer:
78.6m of fencing
That would cost $982.50
Step-by-step explanation:
Perimeter: 2(22.7)+2(16.6)=P
P = 78.6
Cost: 78.6*12.50
C = 982.50
Answer:

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
