Question

The length and the breadth of a rectangular field is 480 and 255 find the length of wire required to fencing it also find the cost of fencing rupees 7 per metre​

Answer 1

Given,

• The length of the Rectangular Field = 480 m
• The Breadth of the Rectangular Filed = 255 m

To Find,

• The length of wire required to fencing .
• The Cost of fencing ₹7 per meter

Solution :

$\mapsto \underline{\sf{\pink{Firstly, \ We \ Find \ the \ Length \ of \ Wire :}}}$

║ ∵The Perimeter of Rectangle = Length of Wire ║

$\boxed{\large{\sf{\therefore \ We \ know \ that :}}}$

$\implies \sf{Perimeter \ of \ Rectangle = \sf{\red{2(Length + Breadth)}}}$

$\implies \sf{Perimeter \ of \ Rectangle = 2(480m + 255m)}$

$\implies \sf{Perimeter \ of \ Rectangle = 2(735m)}$

$\implies \sf{Perimeter \ of \ Rectangle = \boxed{\sf{\pink{1470m}}}}$

$\underline{\boxed{\mathsf{\red{\therefor The \ Length \ of \ Wire = 1470m :}}}}$

$\mapsto \underline{\sf{\pink{Now , \ We \ Find \ the \ Cost \ of \ Fencing :}}}$

$\implies \sf{Total \ Cost \ Fencing = (Length \ of \ wire \ \times Cost \ per \ Meter)}$

$\implies \sf{Total \ Cost \ Fencing = 1470 \ \times 7}$

$\implies \sf{Total \ Cost \ Fencing = \boxed{\sf{\red{Rs.10,290}}}}$

QUESTION :

The length and the breadth of a rectangular field is 480 and 255 find the length of wire required to fencing it also find the cost of fencing rupees 7 per metre.

SOLUTION :

The following information is given..

The length and the breadth of a rectangular field is 480 m and 255 m respectively.

We know that the perimeter of a rectangular field is 2 { L + B }

So, perimeter = 2 { 480 + 225 } m = 1410 m.

Now, the rate of fencing is Rs. 7 per metre.

So,

Cost of Fencing = Perimeter × Rate

=> Cost = Rs. 1410 × 7

=> Cost = Rs. 9870

Answer :

The cost of Fencing is Rs. 9870
