Step-by-step explanation:

Length of the rectangular hall is 110 m and breadth of the rectangular hall is 10 m.

Step-by-step explanation:

Given :-

The breadth of a rectangular hall is 10 m less than its length.

The perimeter of the rectangular hall is 420 m.

To find :-

Its length and breadth.

Solution :-

Let the length of the rectangular hall be x m.

★ The breadth of a rectangular hall is 10 m less than its length.

Then,

Breadth of the rectangular hall = (x-10) m

Formula used :

{\boxed{\sf{Perimeter\:of\: rectangle=2(length+breadth)}}}

Perimeterofrectangle=2(length+breadth)

According to the question,

2(l+b)=420

→ 2 [(x+(x-10)]=420

→ 2 (x+x-10) = 420

→ 2 (2x-10) = 420

→ 2x-10 = 420/2

→ 2x-10 = 210

→ 2x = 210+10

→ 2x = 220

→ x = 110

Therefore,

Length of the rectangular hall = 110 m

Breadth of the rectangular hall = (110-10) = 100 m
