The diagram shows that all the sides of the rectangle are congruent. Since the perimeter all of the sides added up, all you have to do is divide the perimeter by 4.
Therefore, the perimeter, which is 16x + 24, can be divided by 4 to find the length of one side. 
16x + 24/4 = length of one side. So, the length of one side is 4x + 6.
Hope this helped!
        
             
        
        
        
Given:
A man owns 3/4 of the share of a business and sells 1/3 of his  shares for Bir 10,000.
To find:
The value of the business in Bir.
Solution:
Let x be the value of the business.
It is given that a man owns 3/4 of the share of a business and sells 1/3 of his  shares for Bir 10,000.


Multiply both sides by 4.


Therefore, the value of the business is 40,000 Bir.
 
        
             
        
        
        
The area is 7 units squared.
3-1 = 2
5--2 = 7
2x7 = 14
14/2 = 7
        
             
        
        
        
x²+y²-2x-6y-5=0
x²-2x+y²-6y=5
x²-2x+1+y²-6y+9=5+1+9
(x-1)²+(y-3)²=15
(x-1)²+(y-3)²=(V15)²
-> centre of the circle: C(-1,-3) 
-> radius of the circle: V15
