Question

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

Answer 1

Answer:

_______________________

Perimeter of the rectangular sheet = 100 cm

length of the rectangular sheet = 35 cm

Breadth of the rectangular sheet = 2(l + b) = 100

$= 2(35 + b)= 100$

$= 70 + 2b = 100$

$= 2b = 100 – 70$

$b = 30/2=15cms$

$Breadth = 15 cms$

∴ Area = l × b = 35 × 15 = 525 sq.cms

Answer 2

$perimeter \: = 2(l + b)$

$100 = 2l + 2b$

$100 = 2(35) + 2b$

$100 = 70 + 2b$

$2b = 100 - 70$

$2b = 30$

$b = \frac{30}{2}$

$b = 15$

HENCE, BREADTH = 15cm

$area \: of \: rectangle = length \times breadth$

$area = 15 \times 35$

$area = 525 {cm}^{2}$
