Half the perimeter of a rectangular garden whose length is 4 m more than its width is 36 m. What are the dimensions of the garden?
Let the width of the garden = w
Therefore length = w + 4
Perimeter of the garden = 2(length + bredth) = 2(w + 4 + w) = 2(2w + 4)
given that half of the perimeter = 36m
therefore, 2w + 4 = 36
=> 2w = 32
=> w = 16m.
Therefore, length = w + 4 = 20
length, bredth = 20,16
