Let us assume, the length of the pool be "y" m
So, the width of the pool = half the length of the pool +2 = y/2 +2 = [y+4]/2
Here, perimeter of the pool = 97 m
But the perimeter of the pool, by formula = 2( l +b )
Then, our equation becomes
2(l+b) = 97
Putting the value of length and width of the pool, we have
2 (3y +4)/ 2 = 97
i.e. 3y + 4 = 97
i.e 3y = 97 - 4 = 93
So, y = 93/3 = 31
Hence, the length of the pool = 31 m
and breadth of the pool = 31/2 + 2 = 17.5 m
Hope this has helped you to some extent.
