The equation for arithmetic growth is given by:

$L_{t} = L_{0} + r t$

Where:
$L_{t}$ is the length at time $t$
$L_{0}$ is the initial length at time $t = 0$
$r$ is the arithmetic growth rate
$t$ is the time

Given:
$L_{0} = 20$ cm
$r = 30$ cm/day
$t = 7$ days

Substituting the given values into the equation:

$L_{7} = 20 + 30 \times 7$

$L_{7} = 20 + 210$

$L_{7} = 230$ cm
