Arectangular section of wilderness will be set aside as a new wildlife refuge. its dimensions are 5 x 105meters by 4 x104 meters. find the area of the land in square meters. make sure your answer is in correct scientific notation form

Step-by-step explanation:

The area of a rectangle can be calculated with this formula:

Where "l" is the lenght and "w" is the width.

You know that the dimensions of this rectangle are 5*10⁵meters and 4*10⁴ meters, then you need to multiply them to get the area:

Since 10⁵ and 10⁴ have equal base, you must add the exponents:

Scientific notation has the form:

Where "a" is any number between 1 and 10 but less than 10, and "n" is an integer.

Since 20 is greater than 10, you must move the decimal point to the left:

Rewriting the result, you get:

maya’s expression will generate the wrong sum because she violated the commutative property.
