Answer 2

Answer: The cost of fencing is  476 Rs when area of square field is 1156m².

Step-by-step explanation:

Area of square field= 1156m²

side x side = 1156m²

side²= 1156m²

side= √1156

       =34m

Fencing requires covering the border area

The perimeter of the square=4 x sides

                                              =4x 34=136m

  cost of fencing for 1 m    = Rs 3.50

∴cost of fencing for 136m = Rs 136 x 3.50

                                           =Rs 476

Hence, the cost of fencing is  476 Rs when area of square field is 1156m².
