Question

If the length of a rectangular piece of marble is 3x units and breadth is 5y units , Then find its area?

Answer 1

Answer:

The area of rectangle is 15xy

Step-by-step explanation:

ares of rectangle =l*b

=3x*5y

=15xy

Answer 2

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 3x cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 5y cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$ $\tt Area = Length \times breadth \\ \\ \tt \longrightarrow Area = 3x \times 5y \\ \\ \longrightarrow \boxed{\bold{\underline{\red{Area = 15xy\:sq.units}}}}$
