alexdok [17]

Answer:

The correct answer is 1.2913 x 10^{5} square feet.

Step-by-step explanation:

A factory builds a new warehouse that is approximately 1.28 x 10^{5} square feet = 128,000 square feet.

Later, they add on 1.13 x 10^{3} square feet = 1,130 square feet more for offices.

Thus the total size of the new building is given by 128000 + 1130 = 129130 square feet = 1.2913 x 10^{5} square feet.

Thus in scientific notation the total area of the factory is 1.2913 x 10^{5} square feet.
