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

Answer:

781200 cm or 7.81200x10^5 cm

Step-by-step 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
