Hint: You should know the conversion of the unit. Like you should know $1m = 3.28ft$. You can use this and get your required answer. While substituting the values make sure that all the quantities have the same unit.

Here in the question, it is given that the car whose length is $4m$ and the boat whose length is $8m$.
And we need to calculate the total length, that means,
Sum of length of car and length of boat ( in $ft$)
So, first of all, we have to change the unit from $metre$ to $ft$.
You must be knowing the value of unit changing for eg., $1m = 100cm$
Like this, $metre$ and $ft$ are also related.
The relation is given by the equation
$1m = 3.28ft$
So as we know that $1m = 3.28ft$, so we can find the length of car and boat in $ft$.
So, let us calculate the required length. First we will convert the length of car in $feet$.
Now according to question, length of car is given $4m$.
As we know $1m = 3.28ft$,
So, for $4m$, it will be
$4m = 4 \times 3.28 = 13.12ft$
Now similarly we need to find the length of boat which is equal to $8m$
As we know $1m = 3.28ft$,
We can find the measurement of $8m$in $ft$ as
$8m = 8 \times 3.28 = 26.24ft$
Now we come to know that
Length of car$= 13.12ft$
Length of boat$= 26.24ft$
Now we need to find the sum of length of car and boat in $feet$
$=$length of car + length of boat
$= 13.12ft + 26.24ft \\ = 39.36ft \\$
So, it is close to $39.37ft$, so our answer is option C.

Note: You must know the unit conversion. For example,
$1m = 3.28ft$
$1m = 100cm$
And so on. This is all you should learn then you can solve these questions quickly and save your time.
