➪ Given,

➣ Perimeter of rectangular sheet =100 cm

➣ Length of Rectangular sheet = 35 cm

➪ To Find,

➣ Breadth of Rectangular sheet

➣ Area of Rectangular sheet

⇰ Perimeter = 2(length + breadth)

⇒ 100 = 2(35 + b)

⇒ 100 = 2 × 35 + 2 × b

⇒ 100 = 70 + 2b

⇒ 2b = 100 - 70

⇒ 2b = 30

$⇒ b \: \: = \: \cancel\frac{30}{2}$

⇒ b = 15 cm

➣ Length = 35 cm

➣ Breadth = 15 cm

⇰ Area = length × breadth

⇒ Area = 35 × 15

⇒ Area = 525 cm²

➣ So, the Breadth of the rectangular sheet is 15 cm and the area of the rectangular sheet is 525 cm²..
