Explanation:

Dimensions of a rectangular plot:

Let \: Length = l \: m \: and \: breadth = b \: m

 i) Perimeter \: of \: the \: plot = 36 \: m

 \implies 2( l + b ) = 36

 \implies l + b = \frac{36}{2}

 \implies b = 18 - l \: --(1)

 ii ) Area \: of\: the \: plot = l \times b \: --(2)

/* According to the problem given */

 If \: the \: length \: is \: increased \: by \: 6\:m\\and \: the \: breadth \: is \: decreased \: by \\ 3\:m\: then

New Dimensions of the rectangular plot:

 Length = ( l + 6 )\: m \: and \\breadth = ( b - 3 ) \: m

 Area \: of \: the \: new \: plot = ( l+6)(b-3) \:--(3)

 \pink{ (l+6)(b-3) = l \times b }

 \implies l( b-3) + 6( b -3 ) = lb

 \implies \cancel {lb} - 3l + 6b - 18 =\cancel { lb}

 \implies -3l + 6b - 18 = 0

/* Dividing each term by 3 , we get */

 \implies - l + 2b - 6 = 0

 \implies - l + 2( 18 - l ) = 6\: [ From \: ( 1 ) ]

 \implies - l + 36 - 2l = 6

 \implies - 3l = 6 - 36

 \implies -3l = -30

 \implies l = \frac{ -30}{-3}

 \implies l = 10

Therefore.,

 \red{ Length \: of \: the \: plot } \green { = 10\:m }
