\(R_{1}=\left \{ (x,y)|0\leq x\leq 2,\: \, 0\leq y\leq 1 \right \},\;\)

\(R_{2}=\left \{ (x,y)|\, 0\leq x\leq 2,\: 1\leq y\leq 2 \right \}, \:\: \;\)

\(R =\left \{ (x,y)|0\leq x\leq 2,\: 0\leq y\leq 2 \right \} .\)

 

Jika \(\iint_{R} \: g(x,y)dA = 5\) dan \(\iint_{R_{1}} \: g(x,y)dA = 2\) ,

 

hitunglah

\(\iint_{R_{2}} \: (2g(x,y)+3)dA.\)
