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:

The breadth is 15 cm and area is 525 cm².

Step-by-step explanation:

Given :

• The perimeter of a rectangular sheet = 100 cm

• The length of rectangular sheet (l) = 35 cm

To find :

• Breadth (b) and Area rectangular sheet

Solution :

★ Perimeter of Rectangle = 2 (l + b)

⇒ 2 (l + b) = 100

⇒ 2 (35 + b) = 100

⇒ 70 + 2b = 100

⇒ 2b = 100 - 70

⇒ 2b = 30

⇒ b = 30 / 2

⇒ b = 15

Breadth = 15 cm



★ Area of Rectangle = (l × b)

⇒ 35 × 15

⇒ 525 cm²

∴ The breadth is 15 cm and area is 525 cm².

Answer 2

Explanation:

PERIMETER OF RECTANGLE=2(length+breadth)

given perimeter is 100cm

given length is 35cm

let the breadth be 'b'

=>100=2(35+b)

=>50-35=b

=>15=b

the breadth of rectangle is 15cm

AREA OF RECTANGLE=length×breadth

=>35×15

=>525cm^2

the area of rectangle=525cm^2
