Question

15. Find the cost of fencing a rectangular field 105m long and 75m broad at the rate of
5.75 per metre.​

Answer 1

Step-by-step explanation:

length = 105 m

breadth = 75 m

Rate of fence = 5.75 p/m

First find the perimeter:

P of rectangle = 2×(l + b)

=2(105m + 75m)

=2(180m)

P= 360 m

Cost of fencing = 360m×5.75= Rs 2070. Ans
