Answer:

Step-by-step explanation:
The circumference of circle G is 2pi, which means that HJ is equal to 81/360*2pi = 9pi/20, which means that RJ is equal to 18pi/20-9pi/20 = 9pi/20. Therefore, RHJ is equal to the circumference of the area minus RJ, which is equal to 40pi/20 - 9pi/20 = 31pi/20

The breadth of rectangle is 14 cm
The perimeter of rectangle is 65 cm
<em><u>Solution:</u></em>
Given that,
Area of rectangle = 259 square centimeter
Length of rectangle = 18.5 cm
<em><u>The area of rectangle is given by formula:</u></em>

<h3><u>Find the breadth:</u></h3>
Substitute the given values in above formula:

Thus breadth is 14 cm
<h3><u>Find the perimeter:</u></h3>
The perimeter of rectangle is given by formula:

Substitute the given values in above formula:

Thus perimeter of rectangle is 65 cm
 
        
             
        
        
        
The equation for a circle is 
(x-h)² + (y-k)² = r²
h = your given x 
y = your given k 
Let's plug everything in! 
(x - 5) ² + (y - (-1)) ² = 12²
Your final equation is 
(x - 5) ² + (y + 1) ² = 144
