Step-by-step explanation:

The perimeter is= 2(8.5+6.5)= 2*15= 30 m

Answer 2

──────────────────

Gɪᴠᴇɴ -

Length = 6.5

Breadth = 8.5

──────────────────

Fᴏʀᴍᴜʟᴀ -

Pᴇʀɪᴍᴇᴛᴇʀ Oꜰ Rᴇᴄᴛᴀɴɢʟᴇ = 2 × (l + b)

──────────────────

Sᴏʟᴜᴛɪᴏɴ -

So,

Pᴇʀɪᴍᴇᴛᴇʀ Oꜰ Rᴇᴄᴛᴀɴɢʟᴇ ABCD

= 2 × (l+b)

= 2 × (6.5 + 8.5)

= 30 cm
