Question

<br /> Length and breadth of a floor is 30 m and 25 m respectively. Find the length of such a longest rope whi<br />can measure the length and breadth of room completely.<br />​

Answer 1

Correct Question;

Length and breadth of a floor is 30m and 25 m respectively . Find the length of such a longest rope which can measure the length and breadth of floor of the room compeletly .

Step-by-step explanation:

♤ Given :

Length of room = 30m

Breadth of room = 25m

♤ To Find :

length of longes rope that cover the legth and breadth compeletly .

So basically it has asked to find such a length that is the sum of whole floor's length and breadth . we know that perimenter is the sum of all sides of a given figure . so what are you waiting for ?

$\bold \red{perimeter \: of \: rectangle \: = 2(l + b)}$

$= > \: \: 2(30 + 25) \\ = > \: \: 2(55) \\ = > \: \: 110cm$

a 110 cm rope is required to cover whole length and breath compeletly .
