Question

20. What is the area of a rectangle with length 4 cm and breadth 2 cm?​

Answer 1

8$cm^{2}$

Area of the rectangle:

The area is the territory occupied by a rectangle inside its 4 sides or limits.

How to Calculate a Rectangle's Area

To locate the location, follow the steps below:  

Step 1:  

Takedown the length and breadth measurements using the given information.  

Step 2:

Multiply the given length and breadth values.

 Step 3:  

In square units, write the solution.

 Given,  

Length   = 4cm  

Breadth = 2cm

Area of the rectangle= length*breadth  

                                 = 4*2  

                                 = 8

The area of the rectangle is $8cm^{2}$.

Answer 2

Answer:

The area of a rectangle is $8cm^2.$

Step-by-step explanation:

As per the data given in the above question,

Given that:-

The length of a rectangle = $4cm$

The breadth of a rectangle = $2cm$

We have to find the area of a rectangle,

A rectangle is a four-sided two-dimensional plane figure.

The rectangle is a type of parallelogram that has all of its angles equal.

The area of a rectangle is calculated by multiplying the length and breadth of a rectangle.

Here we have to use the formula of the area of a rectangle,

i.e., $A = l\times b$

Where, l = length  

            b = breadth

Given:- l = $4cm$ and b = $2cm$

Substitute the given values of length and breadth in the above formula we get,

$A = 4\times 2$

Multiplying $4$ by $2$, we get

$A =8cm^2$

Hence, the required solution is $8cm^2.$
