, the width of the rectangle is

, and the area of the rectangle is A. Then we have

. Assume the length of the rectangle is A, the breadth of the rectangle is B, and the area of the rectangle is A. We know that the length of the rectangle is 8 cm and the area of the rectangle is

. We can now calculate the value of breadth using the formula

.
It was given that the area of the rectangle is equal to

and the length of the rectangle is equal to

.
We know that if the length of the rectangle is

and the breadth of the rectangle is

then the area of the rectangle is equal to

where

.
So, we get

Let's pretend the rectangle's width is equal to B.

By using cross multiplication, we get

Now we will substitute equation (

) and equation (

) in equation (

So, the breadth of the rectangle is equal to

.
Hence, the correct option is 1
