17429- 5 = 17424  [he had 5 men over]

$\textrm{according to the question it structures look like$n*n$square.}$

$\textrm{there are$n^{th}$row and each row is dividing into$n^{th}$coloum.}$

$\textrm{now it’s given that$5$men's are extra here.}$

$\implies$ $n*n=17429-5$

$\implies$ $n^2=17424$

$\implies$ $n=132$

$\textrm{so the number of men in front row is 132.}$
