Step-by-step explanation:
Given that:
Initially, Taki has her back to a wall and then starts walking straight forward.
Kindly refer to the diagram attached in the answer area.
Initially, Taki was at point A and then moves towards point B.
At point B, Taki turns
and then starts walking to reach point C at the wall.
To find:
The angle
that her body is making with the wall.
Solution:
As per question statement:

We know that angle on straight line is always 
i.e.

Now, using the angle sum property of a triangle in
:

So, our answer is: 
Step-by-step explanation:
Dividing the shape into two:
The area of the rectangle is
A= 13.5*4.8= 64.8km2
the area of the triangle
A = [( 5.7-4.8) *13.5 ]/ 2= 6.075km2
Therefore the total area is
At = 64.8 + 6.075 = 70.875km2
