Answer 2

Answer:

Let the breadth of the hall be x metres.

Then, the length of the hall = (x + 5) metres.

According to question,

Perimeter of the hall = 74 metres

=> 2 (x + x + 5) = 74

=> 2 (2 x + 5) = 74

=> 4 x + 10 = 74

=> 4 x = 74 - 10

(Transposing 10 to R.H.S.)

4x = 64

=> 4x = 64

(Dividing both sides by 4)

=> x = 16

Breadth of the hall = 16 metres and length of the hall = 16 + 5 = 21 metres.
