Question

Find the breadth of a rectangular playground, if its area is 460 m' and the length is 23 m. Also find its
perimeter.
​

Answer 1

Answer:

B = 20 , perimeter = 86

Explanation:

Area = L× B

= 23 × X

460 = 23 X

X = 460÷23

X = 20

perimeter = 2(L+B)

= 43 × 2

= 86

Answer 2

ᴀʀᴇᴀ ᴏꜰ ʀᴇᴄᴛᴀɴɢʟᴇ = 460ᴍ²

ʙʀᴇᴀᴅᴛʜ = 23ᴍ

⇒ ᴀʀᴇᴀ ᴏꜰ ʀᴇᴄᴛᴀɴɢʟᴇ = ʟ × ʙ

ʟ × 23 = 460

ʟ = 460/23

ʟ = 18.26

⇒ᴘᴇʀɪᴍᴇᴛᴇʀ = 2 ( ʟ + ʙ )

= 2 ( 18.26 + 23 )

= 2 × 41 .26

= 82.52 [ᴀɴꜱ]
