Let R denote a rectangular metal plate given by the region [2, 10] × [2, 6] in the y-plane, with xand y given in centimeters. Suppose that the density of the plate is given by p(x, y) = x +y grams/cm2. Use Ax = Ay = 2 and an appropriate Riemann sum to estimate the mass of this plate. Find both an upper and lower estimate of the mass by using appropriate corners of each subrectangle and then average your values to give a better estimate of the exact mass of the plate. Show work and include units with your answer.

Simple calculus question. I will rate like. Thank you.

Let R denote a rectangular metal plate given by the region [2, 10] × [2, 6] in the xy-plane, with
xand y given in centimeters. Suppose that the density of the plate is given by
p(x, y) = x + y grams/cm2. Use Ax = Ay=2 and an appropriate Riemann sum to estimate the
mass of this plate. Find both an upper and lower estimate of the mass by using appropriate
corners of each subrectangle and then average your values to give a better estimate of the exact
mass of the plate. Show work and include units with your answer.
