Let the breadth of the garden be y metre So,length becomes( y+4) We know that 2(length +breadth)=perimeter of rectangle. A\c 1/2*2(y+4+y) = 36 2y+4 =36 2y=36-4 y=32/2 y=16 Therefore,we get breadth=y=16m and length=y+4=16+4=20m

Let x be the length and y be the breadth.

{tex}\therefore{/tex} x = y + 4 {tex}\implies{/tex}x - y = 4 --- (1)

P = 2 (x + y)  {tex}\implies{/tex}x + y = 36 --- (2)

(1) + (2) {tex}\implies{/tex}2x = 40 {tex}\implies{/tex}x = 20 m {tex}\implies{/tex} y = 16 m
