Question

In the given figure, DE||BC and PE||DC. If AP=4cm, PB=12cm, find AD.​

Answer 1

ɢɪᴠᴇɴ :

ᴅᴇllʙᴄ

ᴘᴇllᴅᴄ

ᴀᴘ=4ᴄᴍ

ᴘʙ=12ᴄᴍ

ᴛᴏ ғɪɴᴅ :

Aᴅ=?

sᴏʟᴜᴛɪᴏɴ :

(ʙᴇғᴏʀᴇ ғɪɴᴅɪɴɢ ᴛʜᴇ ᴍᴇᴀsᴜʀᴇᴍᴇɴᴛ ᴏғ ᴀᴅ ᴡᴇ ʜᴀᴠᴇ ᴛᴏ ғɪɴᴅ ᴛᴏᴛᴀʟ ᴍᴇᴀsᴜʀᴍᴇɴᴛ ᴏғ ᴀʙ )

sᴏ ,

ᴘʙ+ᴀᴘ = ᴀʙ

12 + 4 = 16

AB=16

$\frac{ᴀʙ}{2} \: = ᴅᴀ \:$

$\frac{16}{2} = ᴀʙ$

8=Aᴅ
