5. The length and breadth of a
rectangular field are 190 m and
100m respectively. The cost of
fencing the field at the rate of Rs.
10 per metre is​

Answer 1

Given :

⬤ Length of Rectangular Field = 190 m .

⬤ Breadth of Rectangular Field = 100 m .

To Find :

⬤ Perimeter of Rectangular Field .

⬤ Cost of Fencing the Field at the Rate of Rs. 100 per metre .

Formula Used :

$\sf[\:{Perimeter\:of\:Rectangle=2(l+b)}\:]$

Solution :

First , We have to Calculate the Perimeter of Rectangular Field . Hence ,

• Length = 190 m
• Breadth = 100 m
• Perimeter = ?

According to the Formula :

2 (l + b)

2 (190 + 100)

2 (290)

580

Therefore , The Perimeter of Rectangular Field is 580 m .

Now :

Cost of Fencing at Per metre = Rs. 10

Cost of Fencing at 580 metre = Rs. 10 × 580

= Rs. 5800

Therefore , Cost of Fencing the Rectangular Field at the Rate of Rs 10 per metre is Rs. 5800 .
