Answer 1

Answer:

12000 square centimeters

Explanation:

Given:

Length(l) of the rectangular poster = 1.5 meters

Width(w) of the rectangular poster = 0.8 meters

To find:

The area of the poster.

Let's go ahead and convert the given dimensions of the poster in meters to centimeters as seen below;

$\begin{gathered} 1\text{ meter = 100 centimeters} \\ So\text{ 1.5 meters = 1.5 * 100 = }150\text{ centimeters} \\ 0.8\text{ meters = 0.8 * 100 = }80\text{ centimeters} \end{gathered}$

So we can go ahead and determine the area(A) of the poster in square centimeters as seen below;

$\begin{gathered} A=l*w \\ =150*80 \\ =12000\text{ square centimeters} \end{gathered}$

So the area of the poster is 12000 square centimeters
