There are 7 smaller squares inside the large rectangle above.

If the green square has side length 1 and the brown square has side length 2, what is the area of the rectangle?

One  1 x 1  square

Three  2 x 2   squares

One  3 x 3  square

One 4 x 4 square

One 5 x 5  square

 

 

1^2   +  3*2^2   +  3^2   +  4^2   +  5^2  =

 

1  +   12  +  9   +  16   +   25   =

 

63
