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

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 2

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

.•. Here's is your Answer

LENGTH = 40m
