Question

Find the area of rectangular plot whose length and breadth are 12cm and 4cm​

Answer 1

Answer:

length= 12 cm

breadth= 4cm

area=length×breadth

=12×4cm²

=48cm²

Answer 2

• $\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 12 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 6 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

Given : Length of Rectangular Plot is 12 cm and Breadth of Rectangular plot is 4 cm .

Need To Find : Area of Rectangular plot .

$\dag\frak{\underline { As,\:We\:know\:that\::}}$

$\star\boxed {\pink{\sf{ Area _{(Rectangle)} = l \times b }}}$

Where ,

• l is the Length of Rectangular Plot and b is the Breadth of Rectangular plot.

⠀⠀⠀⠀⠀⠀$\underline {\bf{\star\:Now \: By \: Substituting \: the \: Given \: Values \::}}$

$:\implies \sf{ Area_{(Rectangle)} = 12 \times 4 }\\\\\underline {\boxed{\pink{ \mathrm { Area_{(Rectangle)} = 48\: cm^{2}}}}}\:\bf{\bigstar}$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm { Hence\:Area \:of\:Rectangular \:plot\:is\:\bf{48\: cm^{2}}}}}$
