Question

The length and breadth of a rectangle are in the ratio of 2:1. If its breadth is 200 m, then find its perimeter

Answer 1

Answer : 1200 m

Solution :
_________

Given that : The Length and breadth of a rectangle are in Ratio of 2:1

Let, the length of rectangle is 2x and breadth of rectangle is x

Also given that : The breadth is 200m

According to the question : Breadth = x = 200m

So, The length will be : 2x = 2×200 = 400 m

As we know that : Perimeter of rectangle

$2(l + b) \\ \\ = > 2(400 +200) \\ \\ = > 2 \times 600 \\ \\ = > 1200 \: m$

So, the perimeter of rectangle will be 1200 m.

Answer 2

Answer : 1200m

Step-by-step explanation :

According to question,

The length and breadth of a rectangle are in the ratio of 2 : 1.

Let the Length - 2x , Breadth - x - 200m

So the length will be -

: 2x

: 2 * 200m

: 400m

Now, Perimeter of rectangle -

= 2 ( l + b )

= 2 ( 400 + 200 )

= 2 * 600

= 1200m. Answer
