The perimeter of a rectangular swimming pool is 64m. If its length and breadth are in the ratio of 5 : 3, find the length of the pool.

Perimeter of swimming pool = 64m (Given)
We know that,
Perimeter = 2(length + breadth). Since length and breadth are in the ratio 5:3,
length = 5x and breadth = 3x
Substituting in the formula for perimeter, we get
64 = 2(5x + 3x)
8x = 32
x = 4
Length of the swimming pool = 5x = 5×4 = 20m
