Question

the breadth and perimeter of a rectangle are 8cm and 64cm . find the length of the rectangle​

Answer 1

Aɴsᴡᴇʀ :-

ʙʀᴇᴀᴅᴛʜ ᴏғ ᴀ ʀᴇᴄᴛᴀɴɢʟᴇ = 8ᴄᴍ

ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ = 64ᴄᴍ

ʟᴇᴛ ʟᴇɴɢᴛʜ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ ʙᴇ x

ᴛʜᴇɴ,

ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ = 2 ( ʟᴇɴɢᴛʜ + ʙʀᴇᴀᴅᴛʜ )

= = > 64 = 2 ( x + 8 )

= = > 64/2 = x + 8

= = > 32 = x + 8

= = > x = 32 - 8

= = > x = 24 ᴄᴍ

ᴛʜᴇʀᴇғᴏʀᴇ ʟᴇɴɢᴛʜ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ ɪs 24 ᴄᴍ

Answer 2

Answer:

The length is 24 cm.

Step-by-step explanation:

Given- breadth:8cm, perimeter:64cm

To find: length

Let the length be x

Perimeter=2(l+b)

64=2(8+x)

64=16+2x

64-16=2x

48= 2x

48/2=x

x=24
