Answer:
Since Akash covers a distance of 48m while going round a square field twice
we have,
2×perimeter=48m
=perimeter = 48m/2
=perimeter=24m
=4 × side=24m
=side=24m/4
=side=6m
Length of wire needed to fence around the square field
=Perimeter of square field
=4×side
=4×6m
=24m
Cost of wire =Rs 1.75×24
=Rs 42
