Answer:
Length=25m
Parameter=100m
5 round cost RS 12500
Step-by-step explanation:
The area of a square
=x²
According to the question the equation is
x²=625
x=√625
x=25
The parameter is
25×4
100 meter
So
1 meter costs 25
100 " " 25×100
 2500
1 round = 100 meter
So
5 round cost 2500×5
 12500
 
        
             
        
        
        
Answer:
Divide the 1st equation by 2 
a + 2c = 19
Divide the 2nd equation by 3
a + c = 13.5
Subtract the 1st equation and the 2nd equation
c = 5.5
Substituting back into the 2nd equation will give:
a + 5.5 = 13.5 
a = 8
