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.
<h3>How to calculate that area?</h3>
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.
