The length of a rectangular field is twice its breadth. If the perimeter of the field is 150 m, find its length and breadth.
Let the length and breadth of the rectangular field be l and b respectively.
According to the question, we have
2(l+b)=150……(i) [∵ Perimeter =150 m]
Given that, l=2b……(ii)
Using eq.(ii) in (i), we have
Hence, the length and breadth of the given rectangle are 50 m and 25 m respectively.
