Question

Find the length of that rectangle whose area is 4900m2 and width is 140m.​

Answer 1

Step-by-step explanation:

Given, area of rectangle = 4900m²

Breadth= 140 m

Let the length of the rectangle be x m.

We know that:- length × breadth= area

:. x × 140 = 4900

x = 4900/140

x = 35

:. The length of the rectangle is 35 m

Answer 2

Given : The width of a rectangle is 140m and the area is 4900m²

$\begin{gathered} \\ \\ \end{gathered}$

To find : What is the length of the rectangle ?

$\begin{gathered}\begin{gathered} \\ \\ \qquad{\rule{200pt}{2pt}} \end{gathered}\end{gathered}$

SolutioN : Calculating the length :

$\begin{gathered} \\ \end{gathered}$

$\begin{gathered} \; \qquad \; :\longmapsto \; \bf \: Area \: = \: length \times width\\ \\ \\ \end{gathered}$

$\begin{gathered} \; \qquad \; :\longmapsto \; \sf \: 4900 \: = \:length \times 140\\ \\ \\ \end{gathered}$

$\begin{gathered} \; \qquad \; :\longmapsto \; \sf \: \cancel\frac{4900}{140} \: = \:length\\ \\ \\ \end{gathered}$

$\begin{gathered} \; \qquad \; :\longmapsto \; \sf \: \frac{35}{1} \: = \:length\\ \\ \\ \end{gathered}$

$\begin{gathered} \; \qquad \; :\longmapsto \; \sf \: 35 \: = \:length\\ \\ \\ \end{gathered}$

$\begin{gathered} \; \qquad \; :\longmapsto \;{\pmb{\underline{\boxed{\red{\frak { length = 35}}}}}} \; \bigstar \\ \\ \\ \end{gathered}$

$\begin{gathered} \\ \\ \end{gathered}$

$\bf \qquad \; \therefore \;$Length of rectangle is 35m

$\begin{gathered} \\ \\ {\underline{\rule{300pt}{9pt}}} \end{gathered}$
