4. A wall in your living room is 23.35 ft long and 15.23 ft high.

a. Calculate the area of the wall (Area = length x height)

b. Report your answer using the correct number of significant figures.

a. Area = 23.35 ft x 15.23 ft = 356.2105 ft^2

b. Report the answer using the correct number of significant figures would be 356 ft^2.

your math is wrong... 23.35 x 15.23 is 355.6205

My apologies for the mistake. The correct calculation is:

a. Area = 23.35 ft x 15.23 ft = 355.6205 ft^2

b. Report the answer using the correct number of significant figures would be 356 ft^2.
