The table below gives values of f(x,y), the number of milligrams of mosquito larvae per square meter in a swamp.
x=0 x=2 x=4
y=0 1 3 6
y=3 2 5 9
y=6 4 8 14
If x and y are in meters and R is the rectangle 0≤x≤4, 0≤y≤6, estimate ∫Rf(x,y)dA.

∫Rf(x,y)dA≈
(Include units in your answer.)
Hint: Evaluate the Riemann sums using the lower left corners and upper right corners. Then take the average of the two Riemann sums.
