A rectangular carpet has an area of 120 sq metres and a perimeter of46 metres. The length of its diagonal (in metres) is:

• According to the question,
  2(l+b)=46
  l+b=23.......(1)
  lb=120........(2)
  from 1 & 2 we get l-b=49.......(3)
  after solving 1 & 3 we get l=15
  b=8
  here,
  b becomes permendicular & l becomes base of the triangle.
  so diagonal becomes hyperphethumes..
  applying phytaghorous theorem,diagonal=17metres...
