Question

A field is in the shape of a rectangle whose length is 130 m and breadth is 95 m
respectively. Find the cost of fencing the field at 20 per metre.​

Answer 1

Answer:

perimeter = 2×[l×b]

= 2 ×(130+ 95)

= 2×225= 450

so the cost will be = 450×20= 9000

answer. 9000rs

Answer 2

Answer:

Given; l= 130m , b = 95 m , Rate of fencing = Rs. 20 per m²

length of fence = Perimeter of field (rectangle)

= 2(l+b)

= 2(130+95)

=2* 225

= 450 m²

Cost of fencing = Rate * Perimeter

= 20 * 450

= Rs . 9000
