Question

the perimeter of a reactangle is 51.8 m and its length is 16.5 m . Find the breadth and the area of the reactangle​

Answer 1

(l )Length= 16.5m

(P) Perimeter= 51.8m

Using the formulas

• A=wl
• P=2(l+w)

Solving forA

A=P(l/2)﹣l²

=51.8(16.5/2)﹣16.52

≈155.1m²

Answer 2

Sᴏʟᴜᴛɪᴏɴ :-

Pᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ =51.8ᴍ

ʟᴇɴɢᴛʜ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ =16.5ᴍ

Pᴇʀɪᴍᴇᴛᴇʀ = 2 ( ʟ + ʙ)

➡ 2(16.5 + ʙ) = 51.8

➡16.5+ ʙ = 51.8/2

➡ʙ = 25.9 - 16.5

➡ʙ = 9.4 ᴍ

Aʀᴇᴀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ = ʟᴇɴɢᴛʜ * ʙʀᴇᴀᴅᴛʜ

➡ = 16.5 * 9.4

➡ =155.1ᴍ^2

Tʜᴇ ʙʀᴇᴀᴅᴛʜ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ ɪs 9.4 ᴍ.

Tʜᴇ ᴀʀᴇᴀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ ɪs 155.1 ᴍ^2.
