Answer: rs 4800, rs 3456
Step-by-step explanation:j
given data:
length of a sid = 48m
cost of ploughing the field = rs 25/m
cost of fencing the field = rs 18/m
solution:
we know a square has four equal sides. so total length of the field is
= m ( 48 + 48 +48 + 48 )
= 192m
cost of ploughing the field
= 192m * rs 25
= rs 4800
cos of fencing the field
= 192m * rs 18
= rs 3456
