Answer 1

Answer :

• Rs.33600 is the cost of fencing the field at the rate of rupees 60 per meter

Given :

• Length of rectangular field is 160m
• Breadth of rectangular field is 120m

To find :

• Perimeter of rectangular field
• Cost of fencing

Solution :

As we know that,

• Perimeter of rectangle = 2(l + b)

Where , l is length and b is breadth

》Perimeter of rectangle = 2(length + breadth)

》2(160 + 120)

》2(280)

》560m

Hence , Perimeter of rectangular field is 560m

Now , we have to find the cost of fencing

Given that,

• Rate of rupees 60 per m

》560 × 60

》33600 Rs

Hence , Rs.33600 is the cost of fencing the field at the rate of rupees 60 per meter

Answer 2

Answer :

Rs.33600

Given :

Length of rectangular field = 160m

Breadth of rectangular field = 120m  

As we know that

Perimeter of rectangle = 2(L + B)

Where , L is length and B is breadth

Perimeter of rectangle = 2(length + breadth)

=>2(160m + 120m)

=>2(280m)

=>560m

Hence, Perimeter of rectangular field is 560m

Now, we have to find the cost of fencing

Rate of fencing one meter = Rs.60

560m ×Rs.60

Rs. 33600  

Hence, The cost of fencing the field at the rate of rupees 60 per meter is Rs.33600
