B. The solution is reasonable because 50 times 60 is 3,000, which is close to the computed area.
C. The solution is unreasonable because there are four decimal places in the factors and only three decimal places in the product.
D. The solution is reasonable because there are four numbers to the left of the decimal in the factors and four numbers to the left of the decimal in the product.
