Question

A rectangular piece of land measures 0.5km by 0.3km. if it is to be fences with 4rows of wire all long its four sides, find the cost of fencing if 1m of wire costs ₹2​

Answer 1

Answer:

Step-by-step explanation:so,to find the fencing cost required we have to first find the perimeter & multiply it by 4.So,here we go

Required cost of fencing=4×perimeter×2

=

4×2(0.5+0.3)×2

=4×2×0.8×2

=12.8 rupees

Answer 2

1000m = 1km

Thus , sides of rectangle are o.5 × 1000= 500 m

0.3 × 1000= 300m

4 rows are to be weired.

Hence ,

500×4 + 500×4 +300×4+300×4 = 6400m

Thus,

6400 m of wire is required

Cost of fencing is 1m = ₹2

Hence ,

Cost of fencing total farm is 6400 × 2 = ₹12,800

Ans :

Cost of fencing the field with 6400 m wire is ₹ 12,800
