Art is remodeling his living room. it measures 22 feet by 16 feet, and the contractor is charging $32 per square foot. how much is the cost estimate?
a) 5,662
b) 11,264
c) 384
d) 12,842

First, we determine the area of the floor by multiplying the dimensions given. 
                                  Area = Length x Width
                                  Area = (22 ft)(16 ft)
Area is equal 352 m². Then, multiply the calculated area by the surface amount.
                          Total amount = (352 m²)($32)
                                                  = 11,264
Thus, the answer is letter B. 

3.14*1^2=3.14
3.14*3=9.42
9.42 Rounded is 9
