the length of a rectangle is increased by 60%. By what % would the width have to be decreased to maintain the same area?

• If l and b are earlier length and breadth and the length of a rectangle is increased by 60%. the width is decreased to xb to maintain the same area
  
  
  then
  
  l*b = 1.6 *l*x*b
  x= 1/1.6 = 0.625
  
  hence breadth should be decreased by 199*(1-0.625) = 37.5 %

  then
  
  l*b = 1.6 *l*x*b
  x= 1/1.6 = 0.625
  
  hence breadth should be decreased by 100*(1-0.625) = 37.5 %

• The width should also be increased to 60%.

• percentage decrease=(r/((r+100))*100
  = (60/(60+100))*100
  =37.5
