Question

Oliver wants to fence his rectangular garden, whose length is 13 fraction numerator 1 over denominator 3 end fractionmeters and width is 9 fraction numerator 1 over denominator 3 end fractionmeters. Then find the length of the fencing wire he needs to fence his garden.

  1. 24 meters    
  2. 28 meters    
  3. 32 meters    
  4. 36 meters    

hintHint:

Perimeter of any closed figure is sum of length of its side

The correct answer is: 32 meters


    Length of the garden = 13 fraction numerator 1 over denominator 3 end fractionmeters
    Width of the garden = 9 fraction numerator 1 over denominator 3 end fractionmeters
    Perimeter of a rectangle = 2(length + width)
    = 2 open parentheses 13 fraction numerator 1 over denominator 3 end fraction plus 9 fraction numerator 1 over denominator 3 end fraction close parentheses equals 2 open parentheses fraction numerator 40 over denominator 3 end fraction plus fraction numerator 28 over denominator 3 end fraction close parentheses
    equals 2 cross times fraction numerator 48 over denominator 3 end fraction equals 32meters
