1. Answer:

   the formula for perimeter of rectangle is

   the formula for perimeter of rectangle is2(length + breadth)

   + breadth)the length is 5x

   + breadth)the length is 5xthe breadth is 4x

   + breadth)the length is 5xthe breadth is 4xas the ratio is 5:4

   + breadth)the length is 5xthe breadth is 4xas the ratio is 5:4so

   + breadth)the length is 5xthe breadth is 4xas the ratio is 5:4so2(5x+4x)= 108

   2(9x)=108

   2(9x)=10818x=108

   x=108/18

   x=6

   length =5*6=30m

   breadth =4*6=24m
