Let x be the width
2x+3 - length


Using the quadratic formula to get the value of x
x = -3+√(3)²-4(2)(-160)/2(2)
  = (-3+√9+1280)/4
  = (-3+√1289)/4   or  (-3-√1289)/4
  =  32.9/4  or -38.9/4
x= 8.225 or - 9.725

Substituting the positive value of x in the equation then
Width ≈ 8.225 m
Length ≈ 19.45 m

Then the length is approx. 19.45 m
