A runner travels around a rectangular track of length 70m and width 30m. After travels around the rectangular track two times, runner back to starting point. Determine distance travelled by the runner.

Given that  l=70m                  b=30m∴ For one complete round, the distance travelled =Total length of rectangle=2(l+b)=2(70+30)=2(100)                      =200m  ∴For two complete rounds, the total distance Travelled  S=2x200                  =400m
