Direct answer :

Width of the enlarged photograph = 14 cm

Length of a small photograph = 6 cm

Width of a small photograph = 4 cm

Length of the photograph when enlarged = 21 cm

Let the width of the photograph when enlarged be x.

Which means :

$= \tt 4 : 6 : : x : 21$

$=\tt (4)/(6) = (x)/(21)$

$=\tt 4 * 21 = 6 * x$

$=\tt 84 = 6x$

$=\tt x = (84)/(6)$

$=\tt x = 14$

Thus, the value of x = 14

Therefore, the width of the enlarged photograph = 14 cm
