Question

If l=8cm and b=4cm,then the are of rectangle=???​

Answer 1

☆ Solution ☆

Given :-

• Length ( l ) of the rectangle is 8 cm

• Breadth ( b ) of the rectangle is 4 cm

To Find :-

• The area of the rectangle

Step-by-Step-Explaination :-

As we know that :-

Area of the rectangle = length ( l ) × breadth ( b )

Where,

• Length ( l ) of the rectangle = 8 cm

• Breadth ( b ) of the rectangle = 4 cm

Putting the respective value,

Area of rectangle = 8 × 4

Area of rectangle = 32

Hence,

The area of the rectangle is 32 cm²

______________________________

Know More :-

Perimeter of Rectangle = 2( L + B )

Perimeter of square = 4 × Side

Perimeter of triangle = AB + BC + CA

Area of Rectangle = L × B

Area of Square = ( side ) ²

Area of Rhombus = Product of Diagonal/2.

Area of Parallelogram = Base × Height.

Area of triangle = 1/2 × base × height .

Answer 2

Correct question :

★ If length is 8cm and breadth is 4cm, then the Area of rectangle ?

${ \bf{ \underbrace{ \purple{Required \: Answer :}}}}$

Given :

• Length of rectangle = 8 cm
• Breadth of rectangle = 4 cm

To Find :

• Area of rectangle ?

Required Knowledge :

$\large\star{\boxed{\sf{\red{ Area _{(rectangle)} = (Length \: \times Breadth)}}}}⋆$

• Now, substitute the values :-

• ⟶ 8 × 4

• ⟶ 32 cm²

■ Hence, the Area of rectangle is 32 cm².

Some formulas to be remembered :-

• Perimeter of rectangle = 2 ( Length + Breadth )

• Area of rectangle = ( Length × Breadth )

• Perimeter of Square = 4 × Side

• Area of Square = ( Side² )

• Perimeter of Triangle = a + b + c

• Area of Triangle = 1 / 2 × Base × Height

• Area of Parallelogram = Base × Height
