Question

A farmer is planning how to use the land in a rectangular field. The rectangle shown represents the field. a rectangle with the bottom labeled 2.5 times 10 cubed feet and the right side labeled 3.3 times 10 cubed feet Part A) If half of the field is used to grow crops, what is the area of the portion of the field that has crops growing? Show every step of your work. (2 points) Part B) Write the final answer in scientific notation with the correct number of significant digits, and label with the correct units. (1 point) Part C) Explain how you chose the number of significant digits in the final answer. (1 point)

Answer 1

The area of the portion of the field that has crops growing is 4.125 × 10^6.

The answer in scientific notation with the correct number of significant digits is 4.125 × 10^6.

The number of significant numbers was based on the calculation.

How to calculate that area?

From the information, the rectangle with the bottom labeled 2.5 times 10 cubed feet and the right side labeled 3.3 times 10 cubed feet.

The area of the portion of the field that has crops growing will be:

= 1/2 × 2.5 × 10³ × 3.3 × 10³

= 4.125 × 10^6

Therefore, the answer in scientific notation with the correct number of significant digits is 4.125 × 10^6 and the number of significant numbers was based on the calculation.
