To find the total area of the tape, we need to multiply the length of the tape (1.14×10^4 mm) by the width of the tape (12.7 mm).
1.14×10^4 mm * 12.7 mm = 14.478×10^4 mm^2
This can be written in scientific notation as 1.4478×10^5 mm^2.
Therefore, the correct answer is A. 1.4478×10^5 mm^2.
A tape dispenser holds 1.14×10^4 mm of tape that is 12.7 mm wide. Multiply the two numbers to find the total area in square millimeters of tape. Write the product in scientific notation.(1 point)
