Let's denote the length of the pool as L and the breadth as B.
According to the given information, the perimeter of the rectangular swimming pool is 154m. The formula for the perimeter of a rectangle is given by:

Substituting the given value of the perimeter, we have:

Dividing both sides of the equation by 2, we get:

We are also given that the length of the pool is 2m more than twice its breadth. Mathematically, we can express this as:

Now we can substitute this value of L in terms of B into the equation we obtained earlier:

Simplifying the equation, we have:

Subtracting 2 from both sides of the equation, we get:

Dividing both sides of the equation by 3, we obtain:

Now we can substitute this value of B into the equation for L:

Simplifying the equation, we have:

Therefore, the length of the pool is 52m and the breadth is 25m.
Using the transpose method, we can rearrange the equation
to solve for L:

Then, substituting this expression for L in the equation
, we have:

Adding B to both sides of the equation, we get:

Subtracting 2 from both sides of the equation, we obtain:

Finally, dividing both sides of the equation by 3, we find:

By substituting this value of B back into the equation
, we get:

Hence, the length of the pool is 52m and the breadth is 25m.
