Answer 2

Greetings of the day !

Let us solve the problem in a step-by-step fashion without further ado :-

SOLUTION :-

Given,

side s of square field = 25 m

Fencing is concerned with the boundaries , so we need to find the permimeter of the field , as :

perimeter p of square field = side × 4

                                             = (25 × 4) m

                                             = 100 m

Cost of fencing per metre = Rs 22.50

∴ Cost of fencing the whole perimeter = Cost of fencing 1 m × Perimeter

                                                                =  Rs (22.50 × 100)

                                                                = Rs 2250

ANSWER : Hence , the cost of fencing a square park of 25 m at 22.50 pr metre is Rs 2250
