Question

If the perimeter of a squared ground is 220m, find the length of a wire
required to fence with
(i) 1 round
(ii) 2 rounds
(iii) 3 rounds

Answer 1

Answer:

for 1 round it is 220m

ii) 440m

iii) 660m

just multiply number of rounds with the perimeter

Answer 2

To find : length of a wire required to fence with

            $( i) \ 1 \ round\\( ii)\ 2 \ rounds\\(iii) \ 3 \ rounds$

Given : perimeter of square = $220 \ m$

Solution :

• Perimeter of square : it is the total length of boundary of a square .
• To find perimeter we add all four length of square .
• As we know all the sides of square are equal, then let 'a' be the length of side then  formula to find perimeter is

                  perimeter $= 4\ a$

• we are given that perimeter of squared ground is $220 \ m$.
• to find length of wire to fence with number of rounds , we multiply number of round  by perimeter.

1. for 1 round :

        length of wire $= 1 \times 220 \ m$

                                 $= 220 \ m$

     2. for 2 rounds :

         length of wire $= 2 \times 220 \ m$

                                  $= 440 \ m$

      3. for 3 rounds :

           length of wire $= 3 \times 220 \ m$

                                    $= 660\ m$

Hence , length of wire required for fencing for1 1  round , 2 rounds , 3 rounds is $220\ m, 440\ m , 660\ m$ respectively .
