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:

The perimeter is 1200

Step-by-step explanation:

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 give that : the breadth is 200m

According to the question : breath = x = 200m

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

As we know that : Perimeter of rectangle

= 2 ( l + b)

= 2 (400 + 200)

= 2 × 600

= 1200m

So, the perimeter of a rectangle is 1200m
