Plz give the answer urgent
​

Answer 1

Answer:

12cm^2

Step-by-step explanation:

Area of rectangle= Length×Breadth

Area= 4×3

Area=12cm^2

Answer 2

Answer:

The area of the rectangle = 12 cm²

Step-by-step explanation:

Given :

Length of the rectangle = 3 cm

Breadth of the rectangle = 4 cm

To find :

The area

Taken :

To find the area of the rectangle use this formula -:

$\boxed{\sf{A=L\:\times\:B}}$

Where,

A = Area of the rectangle

L = Length

B = Breadth

Solution :

$\leadsto\sf{A=3cm\times4cm}$

$\leadsto\sf{A={12cm}^{2}}$

So , the area of the rectangle is 12 cm² .

Extra :

To find the perimeter of the rectangle use this formula -:

$\boxed{\sf{P=2(L+B)}}$

Where,

P = Perimeter

L = Length

B = Breadth

Perimeter -:

$\leadsto\sf{P=2(3cm+4cm)}$

$\leadsto\sf{P=2\times7cm}$

$\leadsto\sf{P=14cm}$

So , the perimeter is 14 cm .
