Question

find the cost of fencing a rectangular field 40 m long and 22 M wide at rupees 10 per metre​

Answer 1

Answer:

In order to find the cost, we need to find the perimeter of the field and then multiply by 16.

Length (l) of field = 62 m

Breadth or width (b) of field = 33 m

Perimeter = 2(l+b)

               = 2(62 m + 33 m)

               = 2 × 95 m

               = 190 m

Cost of fencing per m = Rs. 16

Cost of fencing per 190 m = Rs. 16 × 190 = Rs. 3,040

Hence, answer is Rs. 3,040

Answer 2

Length of Rectangular Park = 40 m

Breadth of Rectangular Park = 22 m

Perimeter = 2 ( l + b )

= 2 ( 40 + 22 )

= 2 * 62

Perimetre = 124 m

Cost of Fencing = Perimeter * Rate per m

= 124 * 10

= ₹ 1240

Cost = ₹ 1240
