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

Answer:

Given :

Perimeter of Rectangular Sheet = 100 cm

Length of Rectangular Sheet = 35 cm

To Find :

Breadth and Area .

Formula Used :

PerimeteofRectangle=2(l+b)

Solution :

2 (l + b) = 100

2 (35 + b) = 100

35 + b = 100/2

35 + b = 50

b = 50 - 35

b = 15 cm

So , The Breadth of the Rectangular Sheet is 15cm .

Formula Used :

AreaofRectangle=l×b

35 × 15

525 cm²

Therefore , The Area of the Rectangular Sheet is 525 cm².
