If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
The first one is correct.
DC=AC
Answer:

Step-by-step explanation:
1) For each chart we will fill in 4 rows, as it says, to show 0.4 or 4/10
2) For this part, we will shade in 4 rows twice, or 8, as it says. This shows 0.4 being multiplied by 2.
b) 8/10 or 0.8 because we have shaded 8 out of the 10 rows, 8/10 = 0.8
c) 0.8 is our answer as we have found out from the above steps

The answer is the second one because if u plug in ⁿ and do the rest of the equation, you get your value
