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 l be the length & w be breadth of the garden
given`l= w+4` (1)
`2(l+w)/2=36`
`l+w=36` (2)
solving eqn (1) & (2) `w+4+w= 36`
`2w=32`
`w=16`
`l=16+4=20`
