Corrected Question

Find the area of rectangle if its both and breath are 7 cm and 3 cm​.

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 7 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 3 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

SOLUTION

Length of the rectangle = 7cm.

Breadth of the rectangle = 3cm.

Area of a rectangle = l × b , Where l is the length and b is the breadth of the rectangle.

Here,

l = 7cm.

b = 3cm.

⇒ Area of the rectangle = 7 × 3

⇒ Area of the rectangle = 21cm².
