Question

The length and breadth of a rectangular hall are 30 m and 27 m respectively. Determine the maximum length of a rope that can measure the length and breadth of the room exact number of times.

Answer 1

$\sqrt{30 { }^{2} + 27 { }^{2} }$
=
$\sqrt{900 + 729}$
=
$\sqrt{1629}$
=
40.3608 is the required for length

Answer 2

Given:

The length and breadth of a rectangular hall are 30meters and 27meters respectively.  

To find:

Determine the maximum length of a rope that can measure the length and breadth of the room exact number of the times

Solution:

From given, we have,

The length and breadth of a rectangular hall are 30meters and 27meters respectively.  

The maximum length of a rope that can measure the length and breadth of the room is equal to the perimeter of the rectangular hall.

The perimeter of the rectangle is given by,

P = 2(l + b)

P = 2(30 + 27)

P = 2 (57)

P = 114 meters

Therefore, the maximum length of a rope that can measure the length and breadth of the room exact number of the times is 114 meters.
