: Sam needs to get carpet in two rooms of his house. Estimate the number of square feet(square footage) in the two rooms if one room measures 10 1/2 feet by 9 3/4 feet; and the other room measures 19 1/4 feet by 18 1/2 feet. This question is from textbook

Estimate by rounding up measurements to the nearest whole number.
Remember if you round down you may not have enough carpet.
10 1/2 = 11
9 3/4 = 10
19 1/4 = 20
18 1/2 = 19

You need about 490 square feet of carpet.
