Question

A farmer has a rectangular field of length and breadth 240m and 180m respectively.
He wants to fence it with three rounds of rope. If the rope costs Rs. 4.5 per meter. Find the cost of fencing.

Answer 1

Length of field = 240 m

Width of field = 180 m

Perimeter of field = 2 ( 240 + 180)

= 2 × 420

= 840 m

Cost of fencing = 3 × Rate of fencing × Perimeter of field

= 3 × 4.5 × 840

= 3 × 45 × 84

= Rs 11340

Answer 2

Hii friend,

LENGTH OF RECTANGULAR FIELD = 240 M

BREADTH OF RECTANGULAR FIELD = 180 M

PERIMETER OF RECTANGULAR FIELD = 2(L+B) = 2(240+180) = 2×420 = 840 M.

LENGTH OF ROPE REQUIRED TO FENCE THE RECTANGULAR FIELD = 3 × PERIMETER OF RECTANGULAR FIELD = 3 × 840 = 2520 M.

COST OF LENGTH OF 1 M = 4.5 RS.

THEREFORE,

COST OF LENGTH OF 2520 = 4.5×2520 = 11340 RS.
