**Hint:**In the question, we have to find what number of feet corresponds to the length $3$ kilometres. We will follow the unitary method to solve the given problem by first searching the equivalent of one unit of kilometre and then multiplying the equation by a number so as to get the required result.

**Complete step-by-step solution:**

The given question requires us to convert and interchange the units of length. We have to convert $3$ kilometres into feet.

We know that each kilometre of length consists of $3281$ feet approximately. So, $1km = 3281ft$.

Let the number of feet that correspond to three kilometres be x.

Then, to convert $3$ kilometres into yards, we follow a unitary method where we first find how many units of feet correspond to a single unit of kilometre and then multiply both sides of the equation by a suitable number so as to get the desired conversion of $3$ kilometres.

So, $1km = 3281ft$.

Now, multiplying both the sides of the equation by $3$, we get,

$ \Rightarrow 3km = \left( {3281 \times 3} \right)ft$

Carrying out the calculations, we get,

$ \Rightarrow 3km = 9843ft$

Hence, the length $3$ kilometres can be converted in the unit feet as $9843$ feet approximately.

**Note:**The kilometres and feet are the units to measure the length of physical commodities or items. A kilometre is abbreviated as km and feet is abbreviated as ft. A kilometre is a metric unit of length and it is used for measuring larger distances lengths as compared to feet.
