The equation of a circle is:
(x - h)² + (y - k)² = radius²
where (h, k) is the center of the circle.
Your center is (- 2, - 7).
Your radius is √81 = 9

Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:

lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).

Answer:
<h2>
93.4 m</h2>
Solution,
Area of rectangle = 159.1 m^2
Length of rectangle = 3.7 m
Breadth of rectangle = ?
perimeter of rectangle = ?
Now,
Area of rectangle = 159.1 m^2
or, length * breadth = 159.1
or, 3.7 * breadth = 159.1
or, 3.7 breadth = 159.1
or, breadth = 159.1 / 3.7
breadth = 43 m
Again,
Finding the perimeter of rectangle:
perimeter of rectangle:
= 2 ( length + breadth)
= 2 ( 3.7 + 43 )
= 2 * 46.7
= 93.4 m
