Answer 1

Answer:

ᴛʜᴇɴ ʟᴇɴɢᴛʜ ᴀɴᴅ ʙʀᴇᴀᴅᴛʜ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ ɪs 17 ᴍ ᴀɴᴅ 4 ᴍ ʀᴇsᴘᴇᴄᴛɪᴠᴇʟʏ.

ᴛʜᴇɴ ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ=2(ʟ+ʙ)=2(17+4)=42

ᴛʜᴇ ʀᴀᴅɪᴜs ᴏғ ᴏɴᴇ ғᴏᴜʀᴛʜ ᴄɪʀᴄʟᴇ ɢɪᴠᴇɴ ɪɴ ғɪɢᴜʀᴇ ɪs 1 ᴍ

ᴛʜᴇɴ ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ᴏɴᴇ ғᴏᴜʀᴛʜ ᴄɪʀᴄʟᴇ=

41 ×(2πʀ)= 41

(2π(1))=

21 π

ᴛʜᴇɴ ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ғᴏᴜʀ ᴏɴᴇ ғᴏᴜʀᴛʜ ᴄɪʀᴄʟᴇ=4×

21

π=2×3.14=6.28ᴍ

ᴛʜᴇɴ ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ sʜᴀᴅᴇᴅ ғɪɢᴜʀᴇ =42−6.28=35.72ᴍ
