Answer 1

Let the width be x.

then length be x+4

A/Q

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.

Answer 2

let the length be 'x' m and breadth be 'y' m.

Now, A.T.Q.

x =  y+4

=>   x-y = 4      -----(i)

also,

36  = x+y     --------(ii)

now adding (i) and (ii)

2x  =  40

x    =  20 m

=> y   =  16 m

hope it helps.
