Turn this into a mixed fraction.
Think : How many times does 54 go into 199??
Well, it goes into 199 3 times! :)
So, do 54 × 3, then subtract that number from 199.
54 × 3 = 162
199 - 162 = 37
So, our remainder is 37.
Our whole number is 3, because that's many times it went into 199.
And our denominator (bottom number) is 54, as it always has been.
So,

The parallel lines have the same slope.
The formula of a slope:

We have the points (2, 5) and (6, -11).
Substitute:

2/8+4/8=6/8 = 2/3 I believe if there isn't some hidden text I don't understand...
3a x 3a x 3a x 3a x 3a
= 243a
Area = Length x Width
Since the pool is a square, you will do 243a x 243a
Area = 59,049
