We want to plant flowers into rectangular flower bed with longer side by one meter longer than its shorter side. Each flower needs \( 1\,\mathrm{dm}^2 \) of free space. From the following functions, choose the one that describes the dependence of the number of planted flowers \( n \) on the length \( a \) of the shorter side of the flower bed. (Assume that the dimensions of the flower bed are given in whole meters.)
\( n=\left(a^2+a\right)\cdot100 \)
\( n=\left(a^2+a\right)\cdot\frac1{100} \)
\( n=(a+1)^2\cdot100 \)
\( n=\left(a^2+a\right) \)
