Question

perimeter of rectangle=101 l=? b=2.5​

Answer 1

Answer:

48

Step-by-step explanation:

l = ?

b = 2.5

Perimeter of a Rectangle = 2(l + b) = 101

2(l + 2.5) = 101

l + 2.5 = 50.5

l = 48

Answer 2

ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ = 2(ʟ+ʙ)

$101 = 2(l + 2.5)$

$101 = 2l + 5$

$2l = 101 - 5$

$2l = 96$

$l = 48$
