The perimeter of a rectangle swimming pool is 194m. Its length is 1m less than 5 times its breadth. What are the length and breadth of the pool?
Given: The Perimeter Of A Rectangle Swimming Pool Is 194m. It's Length Is 1m Less Than 5 Times Its Breadth
To do: Find The Length And The Breadth Of The Pool
Solution
Let the breadth of swimming pool, $b = x$
Length of swimming pool, l = $5x -1$
Perimeter or rectangular pool = $2(l + b) = 2(5x - 1 + x)$
=$ 2(6x - 1) = 12x -2 $
= 194
or $12x = 194 + 2 = 196 $
or$ x = \frac{196}{12}$ = 16.33 m
breadth = 16.33 m; length = $5x - 1 = 5(16.33) - 1 = 80.67 m$
So length = 80.67 m; breadth = 16.33 m
