    Answer:

     \mathfrak{ \huge{ \pink{question : }}}

    ᴛʜᴇ ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ᴀ ʀᴇᴄᴛᴀɴɢᴜʟᴀʀ ᴘʟᴏᴛ ɪs 140 ᴍ. ᴛʜᴇ ᴡɪᴅᴛʜ ᴏғ ᴛʜᴇ ᴘʟᴏᴛ ɪs 30 ᴍ. ғɪɴᴅ ɪᴛs ʟᴇɴɢᴛʜ.

     \mathfrak{ \huge{ \pink{solution : }}}

     \boxed{ \large{ perimeter \:  = 2(l + b)}}

    ʙʀᴇᴀᴅᴛʜ = 30 ᴍ

    ᴘᴇʀɪᴍᴇᴛᴇʀ = 140ᴍ

    140 = 2(l + 30) \\ l + 30 =  \frac{140}{2}  \\ l + 30 = 70 \\ l = 70 - 30 \\ l = 40m

     \mathfrak{ \huge{ \green{hence : }}} \\ the \: length \: is \: 40 \: m.

    Answer:

    Given:

    Perimeter of a rectangular plot = 140m

    Width = 30m

    So,

    Perimeter of rectangle = 2(l+b)

    140 = 2 * (length + 30)

    140/2 = length + 30

    70 = length + 30

    70 30 = length

    length = 40m

    .. Heres is your Answer

    LENGTH = 40m
