Answer:

[tex] 35m [/tex]

Step-by-step explanation:

Given :-

  • The perimeter of a rectangular hall is 120m.
  • Its breadth is 25m .

And we need to find the length of the rectangle . We can use the formula to find the perimeter of rectangle , as ,

Perimeter of rectangle :-

[tex]\implies Perimeter = 2( l + b)[/tex]

  • Let the length of the rectangle be x . Plug in the respective values ,

[tex]\implies 120m = 2 ( x + 25m) \\\\\implies x + 25m =\dfrac{120m}{2}\\\\\implies x + 25m = 60m \\\\\implies x = 60m - 25m \\\\\implies x = 35m [/tex]

Hence the length of the rectangle is 35 m .
