Question

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.

Answer 1

Let the width of the garden be x.
then length be x+4
According to question
l+b=36
x+(x+4)=36
2x+4=36
2x=36-4
2x=32
x=16.
Hence, The length of garden will be 20 m and width will be 16 m.
