The binary operator $\diamond$ is defined as $a \diamond b = 4a + 4b$, and the operator $\square$ is defined as $a \square b = a^2 + b^2$. The calculation for $(3 \diamond 8) \square 2$ is performed as follows: first, $3 \diamond 8$ results in $44$, then $(44) \square 2$ computes to $44^2 + 2^2$. The final result is $1940$, confirming the calculation is correct. The conclusion is that the expression $(3 \diamond 8) \square 2 = 1940$ is accurate.

define the binary operater $\diamond$ by
$a\diamond b$=4a+4b
and $s\square b$ by $a\square b=a^2+b^2$
find
$(3\diamond 8)\square 2=
[(4(3)+4(8))^2 +2^2]=1940$
ok just want to see if this is correct
before i run thru the ribbon :unsure:

This is correct.
 
1940
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
