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.
2028/x=100/30
<span>(2028/x)*x=(100/30)*x </span>we multiply both sides of the equation by x
<span>2028=3.3333333333333*x </span>we divide both sides of the equation by (3.3333333333333) to get x
<span>2028/3.3333333333333=x </span>
<span>608.4=x </span>
<span>x=608.4
so there for its 608.4 hope this helps.</span>
That would be C....(1 x 10^-1) + (6 x 10^-2) + (9 x 10^-3)
