To find the total area of tape in square millimeters, we need to multiply the length by the width.
The length of tape is given as 1.14×10^4 mm and the width is 12.7 mm.
Multiplying these two numbers gives:
1.14×10^4 mm * 12.7 mm = 1.4478×10^5 mm^2
Therefore, the correct answer is A. 1.4478×10^5 mm^2.
A tape dispenser holds 1.14×104 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)
