Academic Mathematics NCERT Class 6

Given:
The length and breadth of three rectangles are:
(a) $9\ m$ and $6\ m$
(b) $17\ m$ and $3\ m$
(c) $4\ m$ and $14\ m$.
To do:
We have to find which rectangle has the largest area and which rectangle has the smallest area.
Solution:
We know that,
The area of a rectangle with length '$l$' and breadth '$b$' is $l \times b$.
Therefore,
(a) Here,
Length $l =9\ m$
Breadth $b =6\ m$
The area of the rectangle $ = 9\ m\times6\ m$
$=54\ m^2$
(b) Here,
Length $l =17\ m$
Breadth $b =3\ m$
The area of the rectangle $ = 17\ m\times3\ m$
$=51\ m^2$
(c) Here,
Length $l =14\ m$
Breadth $b =4\ m$
The area of the rectangle $ = 14\ m\times4\ m$
$=56\ m^2$
The rectangle with an area of $56\ m^2$ is the largest one and the rectangle with an area of $51\ m^2$ is the smallest one.
