The Perimeter of a rectangular swimming pool is 160 feet. Jan wants to swim across the diagonal of the pool. How many times will she have to cross this way to swim at least 200 feet?1
Option 5. Insufficient information
Since the pool is in the form of a rectangle. Therefore opposite sides of the pool are equal.
Let the length of the pool be x and width of the pool is y feet.
Jan wants to swim across the diagonal of the pool therefore length of the diagonal will be = √x² + y²
perimeter of the pool is 16 feet
2(x + y) = 160 feet.
Now to get the length of the diagonal we should know at least one side of the pool.
Therefore information is insufficient for the calculation.
Option 5 is correct.
