Now, we shall find the area of a rectangle.

Let us consider a rectangle

$ABCD$ whose length is

$l \ units$ and breadth is

$b \ units$ .

Then, the area of the rectangle is given by:

Area of the rectangle

$=$ Product of length and breadth

Area of the rectangle,

$A=length \times breadth$

$A=l\times b$

$sq. units$

Therefore, the area of the rectangle is

$l\times b$

$sq. \ units$ .

Example:

1. If the length of the rectangle is

$5 \ cm$ , and the breadth of the rectangle is

$3 \ cm$ , find the area of the rectangle.

Solution:

The length of the rectangle is

$l=5 \ cm$ .

The breadth of the rectangle is

$b=3 \ cm$ .

Area of the rectangle

$=$ Product of length and breadth

Area,

$A=l \times b \ sq. units$

Substituting the values in the formula, we have:

$A=5 \times 3 \ sq. cm$

$A=15 \ sq. cm$

Thus, the area of the rectangle is

$15 \ sq. \ cm$ .
