Question

The perimeter of a rectangular hall is 180 m. If its length is 50 m, find the breadth of the rectangular hall.

plz give me the answer in method.............​

Answer 1

Answer:

perimeter= 2(L+B)

180=2(50+B)

180=100+2B

2B= 180-100

2B=80

B=80÷2

B=40

Breadth=40.

Answer 2

Answer :-

Breadth of Rectangle = 40 m.

Explanation :-

Given :

• Perimeter of Rectangular hall = 180 m.
• Length of Rectangular hall = 50 m.

To Find :

• Breadth of Rectangular hall.

Solution :

We know that,

Perimeter of Rectangle = 2(l + b).

➠ 2(50 + b) = 180.

➠ 100 + 2b = 180.

➠ 2b = 180 – 100.

➠ 2b = 80.

➠ b = 80 ÷ 2.

➠ b = 40 m.

Therefore, Breadth of Rectangle = 40 m.
