A contour map is shown for a function f on the square R = [0, 8] ⨯ [0, 8]. (a) Use the Midpoint Rule with m = n = 2 to estimate the value of f(x,y) dA. R (Round your answer to the nearest integer.) 1952 (b) Estimate the average value of f. (Round your answer to one decimal place.) 30.5 the answers is right. but I don't know how to get those answers so would you please calculate it with dealis how you get those numbers
