Question

Find the area of the rectangle whose length = 9 cm & breadth = 21 cm.​

Answer 1

Answer:

L=9

B=21

Area of rectangle=l×b

=9×21

=189sqcm

Answer 2

Answer:

The area of a rectangle is $189cm^2.$

Step-by-step explanation:

As per the data given in the above question,

Given that:-

The length of a rectangle = $9cm$

The breadth of a rectangle = $21cm$

We have to find the area of a rectangle,

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 = $9cm$ and b = $21cm$

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

$A = 9\times 21$

Multiplying $9$ by $21$, we get

$A = 189cm^2$

Hence, the required solution is $189cm^2.$
