The area of a rectangle of length 2 cm and breadth 1 cm is

(a) 1 cm2

(b) 2cm2

(с) 4 cm2

(d) 8 cm2

☆Required Answer:-

Area of rectangle is 2cm²

$\huge{ \boxed{ \sf{ \red{Option \: A}}}}$

☆Explaination:-

$\large{ \sf{Given : - }}$

➸Lenght:- 2cm

➸Breadth:- 1cm

$\large{ \sf{Finding:-}}$

➸Area of rectangle

$\large \sf{Formula \: Used : - }$

➸Area of rectangle = Length×Breadth

• As per given, let's put all values.

$\implies \sf{Length \times Breadth}$

$\implies \sf{2 \times 1}$

$\implies \sf{2 {cm}^{2} }$

So, the area of rectangle is 2cm².

$\huge{ \boxed{ \sf{ \red{Option \: A}}}}$

Answer 2

The area of this rectangle is (b) 2 cm².

Given:

Length of the rectangle = 2cm.

Breadth of the rectangle = 1cm.

To Find:

We have to find the area of this rectangle.

Solution:

This is a simple problem for Mensuration.

Let us tackle this question.

We can easily solve this question as follows.

According to the question,

The length of the rectangle is 2cm and the breadth of the rectangle is 1cm.

We know that,

Area of a rectangle = length * breadth

So, the area of this given rectangle

= (2 * 1 )cm²

= 2 cm²

Hence, the area of this rectangle is (b) 2 cm².
