Question

Find the indicated values in each of these area
of rectangle is 108 sq.cmte length 12cm, breadth= ?​

Answer 1

Answer:

9 cm

Step-by-step explanation:

Let the breadth be b

Area of rectangle=length×breadth

108 sq. cm=12cm × b

b= 108/12

b=9 cm

Answer 2

Given:

✰ Area of a rectangle = 108 cm²

✰ Length of a rectangle = 12 cm

To find:

✠ Breadth of a rectangle.

Solution:

Rectangle:

• Rectangle is a parallelogram with one of its angle equal to 90°.

The area of a plane figure is the measure of the surface enclosed by its sides. This is measured in square units, i.e, either square centimetre or square metres or in any other square units.

Here in this question, we will use formula of area of rectangle. As we are already provided with the area and the length of a rectangle, putting the values in the formula and then doing the required calculations, we will find the breadth of rectangle.

Let's find out...✧

✭ Area of a rectangle = l × b ✭

Where,

• l is the length of a rectangle.
• b is the breadth of a rectangle.

Putting the values in the formula, we have:

➤ 108 = 12 × b

➤ b = 108/12

➤ b = 9 cm

∴ The breadth of a rectangle = 9 cm

More Formulae:

• Perimeter of a rectangle = 2( length + breadth )

• Length of the diagonal of rectangle = √(a² + b² )

• Perimeter of a square = 4 × side

• Area of a square = ( side )²

• Length of the diagonal of square = √(2 × side )
