You so much in advance and i'd appreciate it!

First you calculate the area of the big rectangle (ignoring the small one the bottom):

A1 = 10 x 6 = 60.

next you calculate the small one:

A2 = 2 x 2 = 4

Now you subtract the small one from the big one and you get:

Area of the figure = A1 - A2 = 60 - 4 = 56

To start off, pretend it's a quadrilateral. It makes everything easier and uses all the numbers.

The area of a quadrilateral is base times height. 
10 = base 
6 = height 

6 * 10 = 60 

That's the value of the original, larger, quadrilateral without the mini quadrilateral that we have to subtract. 

The dimensions of the height and base of the mini quadrilateral are 2 by 2. 
2 * 2 = 4 

Subtract to get your  
60 - 4 = 56
