Hey friend, Harish here.

Here is your answer
______________________________________________________

Given that,

Cost of fencing one meter = Rs 30    

Cost  of fencing whole ground = Rs 15,000.
_ _ _ _ _ _ _ _ _ _ _ _ _ _ 

To find, 
 
The area of  the square.

_ _ _ _ _ _ _ _ _ _ _ _ _ _

Solution,

Let perimeter be " x"

Cost of fencing total Square field =  Perimeter × Cost per meter.
 
                                     $15000 = x (30)$
 
                                             $x = \frac{15000}{30}$
 
                                             $x = 500$
 
 So, perimeter = 500  
_  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 

We know  that, 

$Perimeter = (4)side$

          $500 = (4)side$

         $side = \frac{500}{4}$
   
$side = 125m$
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 

We know that ,

[tex]Area = side^{2} [/tex]
     
         $= (125)(125)$

         $= 15625m^{2}$

Therefore the area of the square field is 15625 cm².
