Question

The cost of fencing a rectangular field at Rs.
40 per metre is Rs. 3200. If the length of the
field is 24m, then its breadth is​

Answer 1

Answer:

Cost of fencing the rectangular field per m = 40/-

Cost of fencing the perimeter of the field = 3200/-

Perimeter of the field = Total cost of fencing / coat of fencing per m =

$3200 \div 40 = 80m$

$we \: know \: that \: \\ perimeter \: of \: the \: field = 2(l + b) \\ 80 = 2(24 + b) \\ 80 = 48 + 2b \\ 80 - 48 = 2b \\ 32 = 2b \\ therefore \\ b = 32 \div 2 = 16m$

Therefore the breadth of the rectangular field = 16m
