Question

find the area of rectangle whose dimensions are:L=16cm,B=12.5cm​

Answer 1

Given,

$l \: = 16cm$

$b \: = 12.5cm$

Now,

$a \: = l \times b$

$a \: = 16 \times 12.5$

$a \: =200 {cm}^{2}$

Answer 2

AnswEr :

• The area of a rectangle = 200 cm².

Step-by-step explanation :

Given that,

• Length of rectangle = 16 cm.

• Breadth of rectangle = 12.5 cm.

And,

• We need to find the area of rectangle.

⋆ Diagram :

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 16 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 12.5 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

We know that, if we are given with the length of rectangle and breadth of rectangle then we have the required formula, that is,

→ Area of rectangle = l × b.

Here,

• l is the length of rectangle.

• b is the breadth of rectangle.

Units,

• The unit of length is cm.

• The unit of breadth is cm.

By using the formula to calculate the area of rectangle and substituting all the given values in the formula, we get :

$\:$

$\sf{\nrightarrow \quad Area_{(rectangle)} = 16 \times 12.5}$

$\:$

$\frak{\nrightarrow \quad \boxed{ \frak{ \pink{Area_{(rectangle)} = 200}}}}$

$\:$

$\therefore \underline{\sf{The \: area \: of \: triangle \: is \: \textsf{\textbf{200}} { \textsf{ \textbf{cm}}}^{ \textsf{ \textbf{2} }}}.}$
