Question

the length and breadth of a rectangle are in the ratio of 2 : 1 if its breadth is 200m then find its perimeter ​

Answer 1

Answer:

breadth = 200

length = 200× 2 = 400

perimeter = 2 ( l + w)

= 2 ( 400 + 200 )

= 1200

Answer 2

Answer :-

Perimeter of Rectangle = 1200 m.

Explanation :-

Given :

• Length and Breadth are in ratio 2:1.
• Breadth = 200m.

To Find :

• Perimeter of Rectangle.

Solution :

Let the dimensions of Rectangle be 2x and x.

It is Given that,

Breadth of Rectangle = 200m.

So,

Breadth = x = 200m.

And,

Length = 2x = 400m.

Now, Calculating Perimeter.

➞ Perimeter of Rectangle = 2(l + b).

➞ Perimeter of Rectangle = 2(400 + 200).

➞ Perimeter of Rectangle = 2(600).

➞ Perimeter of Rectangle = 1200m.

Therefore, Perimeter of Rectangle = 1200 m.
