Q5. Half the perimeter of a rectangular garden, whose length is 4 m more than its width, is 36 m. Find the dimensions of the garden.
Let be the length of the rectangular garden and be the width.
Now, According to the question, the length is 4 m more than its width.i.e.
Also Given Half Parameter of the rectangle = 36 i.e.
Now, as we have two equations, on adding both equations, we get,
Putting this in equation (1),
Hence Length and width of the rectangle are 20m and 16 respectively.
