Answer 1

$\huge\green{\boxed{\sf Answer}}$

Let the breadth of rectangular swimming pool be x metres.

Then, its length =(2x+3) metres.

We know that the Perimeter of a rectangle

=2(Length+Breadth)

=2(2x+3+x)=6x+9

According to the given condition, we have

6x+9=156

⇒6x=156−9 ..[By transposing 9 to RHS]

⇒x=147/6

x=24.5

and length =52cm

length =52cm breadth=24.5cm
