Given:
The number is .
To find:
The a+bi form of given number.
Solution:
We have,
It can be written as
Here, real part is missing. So, it can be taken as 0.
So, a = 0 and .
Therefore, the a+bi form of given number is .
The Quadrilateral is JKLM,
let
be the midpoints of JK, KL, LM and JM respectively.

Given any 2 point P(m,n) and Q(k,l),<span>
the coordinates of the midpoint of the line
segment PQ are given by the formula:
, </span>
-------------------------------------------------------------------------------------------------
thus the coordinates of points
are as follows:
------------------------------------------------------------------------------------------------
The distance between any 2 points P(a,b) and
Q(c,d) in the coordinate plane, is given by the formula:<span>
</span>

thus the distances connecting the opposite entrances can be calculated as follows:
Thus the total distance of the paths joining the opposite entrances is
5+5.39 units = 50 m + 53.9 m = 104 m (rounded to the nearest meter)
Answer: 104 m
