Question

The area of a rectangle is 8.2cm² and its length is 4.1 cm. Find its breadth.​

Answer 1

Answer:

• Breadth of a rectangle is 2 cm.

Step-by-step explanation:

Given that:

• The area of a rectangle is 8.2 cm².
• Its length is 4.1 cm.

To Find:

• Breadth of a rectangle.

Formula used:

• Area of a rectangle = (Length × Breadth)

Finding the breadth of a rectangle:

• According to the question.

⟶ 8.2 = (4.1 × Breadth)

⟶ 4.1 × Breadth = 4.1 × 2

• 4.1 cancelled both sides.

⟶ Breadth = 2

∴ Breadth of a rectangle = 2 cm

More formula of rectangle:

• Perimeter of a rectangle = 2(Length + Breadth)

• Diagonal of a rectangle = √[(Length)² + (Breadth)²]

Answer 2

Given

• Area of rectangle = 8.2 cm²
• Length of rectangle = 4.1 cm

To find

• Breadth of rectangle

Solution

Area of rectangle = Length × Breadth

• 8.2 = 4.1 × Breadth
• 8.2 / 4.1 = Breadth
• 2 = Breadth

Hence, the breadth of rectangle is 2 cm

Verification

• Area = Length × Breadth
• 8.2 = 4.1 × 2
• 8.2 = 8.2
• L.H.S = R.H.S
