Question

The cost of fencing a rectangular park at Rs. 28.50 per metre is Rs.3648.Find its length and breadth if they are in a ratio of 5.3.

Answer 1

Here perimeter of rectangular is = 3648/28.50 = 128 m
Let length of the rectangular is 5x
and                           breadth is 3x
therefor      2( 5x +3x)  = 128 
                  = 8x            = 128 / 2
                  = 8x            = 64
                  = x              = 8
length is = 5 * 8 = 40 m
breadth is = 3 * 8 = 24 m
