Question

A rectangle has length 9.3 x 102 cm and width 8.4 x 102 cm. What is the area of the rectangle?

Answer 1

781200 cm or 7.81200x10^5 cm

Explanation:

Here, you need to solve it with the area equation.

For a rectangle, it's base x height.

In this case, your base will be it's length
`9.3x10^(2) cm` =
`930cm\\`, and its height will be width
`8.4x10^(2) cm` =
`840cm`.

An then you can solve it

`(9.3x10^(2))*(8.4x10^(2))=781200 cm = 7.81200x10^(5)`

Answer 2

9.3x8.4 = 78.12

10^2 x 10^2 = 10^4

answer = 7.812 x 10^5
