Question

Das The Perimeter of
rectangle with sides 10.10
and 9.8cm is equal to the
perimeter of a square find
the side of a square ?​

Answer 1

Step-by-step explanation:

perimeter of rectangle = 2×(l+b)

= 2×( 10.2+9.8)

= 2× 20

= 40

perimeter of square= perimeter of rectangle

4×side= 40

let side be y

4y=40

y= 40/4

y = 10

therefore the side of the square = 10 cm

Answer 2

ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ–

⟹ 2(length+breadth)

⟹ 2(10.10 + 9.8)

⟹ 2 × 19.9

⟹ 39.8 cm

ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ = ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ sǫᴜᴀʀᴇ

39.8 = 4 × side

39.8 / 4 = side

9.94 = side
