Sagot :

The area of the portion of the field used to grow crops is 2.9 x 10³ ft² or 2945ft²

I rounded the final answer to two significant numbers.

What is the area of the portion of the field used to grow crops?

Scientific notation is used in expressing large numbers in smaller numbers. In order to write a number in scientific notation the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

For example, : 1 x 10² is equivalent to 100

The area of a rectangular field = length width

Area of the rectangular field used to grow the crops : 1/2 x (3.1 x 10³) x (1.9 x 10³)

1/2 x (5.89 x [tex]10^{3+3}[/tex])

1/2 x  (5.89 x [tex]10^{6}[/tex])

2.945 x 10³ ft²

= 2.9 x 10³ ft² (rounding off to two significant numbers)
