To find the length of the rectangle, which is 20% more than its breadth, you can multiply the breadth by 1.2.

Let’s say the breadth is x. To find 20% more than x, you can multiply x by 1.2.

So, 20% of x is (20/100) * x = 0.2x.

To find 20% more than x, you add 0.2x to x:

x + 0.2x = 1.2x

Therefore, the length of the rectangle is 1.2x.
