Area of a rectangle = L * W
200 * 100 = 20,000
= 20,000m^2
Convert that to km^2
= 0.02km^2

Answer:

$\frac{2}{7}$

Step-by-step explanation:

In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.

In this case we were already given the points for slope:

$P1=(-4,-4) = (x1,y1)$

$P2=(-2,3)=(x2,y2)$

Slope formula:

$slope = \frac{y2-y1}{x2-x1}$

Now substitute:

$\frac{-2--4}{3--4}$

Solve using KCC: (Keep, Change, Change)

$-2+4=2$

$3+4=7$

= $\frac{2}{7}$

Because the slope isn't a negative you do not need to simplify the answer.

Hope this helps.

Answer:

<u>Given</u>: base = 10.4ft, height = 12.5

Area of octagon = 8(1/2 × b × h)

8(1/2 × 10.4 × 12.5)
520ft²

Volume of pool = 520ft² × 3ft

1560ft³

Now, 1 cubic ft takes 7.5 gallons to fill.

Therefore, 1560 cubic ft takes,

1560 × 7.5
11700

So, <u>Correct choice</u> - [D] 11,700.
