Question 549294
Let the width of picture be=x cm
therefore,length becomes =4/3 of its width(according to given condition)=(4/3)*x cm
since,area of rectangle=length*width
area of this picture(assuming it is rectangular in shape) becomes=(4/3)*x*x
now,the picture is enlarged to 192
so,enlarged area must be equal to=(4/3)x*x=192
x*x=192*(3/4)
x*x=144
taking square root,
x=12
now width=x=12
length=(4/3)*12=16
