Hi! My math proffesor gave me this and, actually I really do not know what to do so if anybody knows something let me know

At the picture below it is a picture (hope u understand it `cause I made it on my own ).

How it is the fastest way to know the area kowing that the result is: 8x 1,25?

Thanks if someone knows how to do this.

The area of the four blocks is 9.9, not 1.25 x 8 = 10. Did you make a mistake? The area of the top block should be 0.625. If that is the case, then its dimensions should be, perhaps: 1.25 x 0.5 =0.625? If that is right, then all you do is add the lengths of the blocks =3.25+2.5+1.75+.5=8 x 1.25 =10.
