Let 
, a reflection over the x-axis consists in the following operation:
If we know that 
and 
, then the points translated over the x-axis are 
and 
, respectively. The most precise description of the shape is a rectangle for the following facts:
1) 
and 
.
2) 
and 
have the same x-component.
3) 
and 
have the same x-component.
4) and have the same y-component.
5) and have the same y-component.
A representation of the shape is included below as attachment.
1) Striangle = 1/2 * (12-8) * 4 = 1/2 * 4 * 4 = 8 km^2
2) Srectangle = 4 * 8 = 32 km^2
3) Sfigure = 8 + 32 = 40 km^2
