Question

A rats angular section of wilderness will be set aside as a new wildlife refuge its dimensions are 5×10 5 m x 4×10 4 m find the area of the land

Answer 1

The area of a rectangle can be calculated with the following expression:

`A=\text{width}\cdot\text{height}`

In this case, we have the width and height given in scientific notation, which means they have a power of 10. In order to multiply two numbers represented in this manner, we need to make both powers have the same exponent, this is done by adding one zero on the first notation.
