Question

the perimeter of a rectangular sheet is 100 cm if the length is 35 find its breadth also find the area ​

Answer 1

Answer:

perimeter of rectangle = 2( length + breadth )

100cm = 2( 35 + breadth )

100cm/2= 35 + breadth

50cm = 35 + breadth

50cm - 35 = breadth

so. breadth = 15cm

Answer 2

Sᴏʟᴜᴛɪᴏɴ:

Tʜᴇ ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ :

$2(l + b)$

$2(35+ b) = 100$

$35+ b = 100 \div 2$

$35+ b = 50$

$b = 50 - 35$

$b = 15$

Tʜᴇ ᴀʀᴇᴀ ᴏғ ᴘᴇʀɪᴍᴇᴛᴇʀ :

$l \times b$

$15 \times 35$

$525 cm^{2}$
