Given :
The Length of the Pool = 15 feet
The Breadth of the Pool = 30 feet
As the Pool is Rectangular in shape :
Perimeter of a Rectangle is Given by : 2(Length + Breadth)
Perimeter of the Pool = 2(15 + 30 ) = 2(45) = 90 feet
We know that Area of Rectangle is given by : Length × Breadth
Area of the Pool = 15 × 30 = 450 feet²
