Question

Diane has a rectangular poster. The poster is 1.8 meters long and 1.25 meters wide. What is the area of the poster in square centimeters?

Answer 1

The area of the rectangular poster is 22500 square centimeters.

Step-by-step explanation:

The area of a rectangle can be found by multiplying its length and width. In this case, the length of the poster is 1.8 meters and the width is 1.25 meters. Therefore, the area of the poster can be calculated as:

Area = Length × Width

1. Convert the length and width to centimeters: Length = 1.8 meters × 100 centimeters/meter = 180 centimeters, Width = 1.25 meters × 100 centimeters/meter = 125 centimeters
2. Calculate the area: Area = 180 centimeters × 125 centimeters = 22500 square centimeters

Answer 2

The area of the poster, in square centimers, is 0.000225 cm².

Step-by-step explanation:

The area of the rectangle is the multiplication of the width and the height.

To find the area in square centimeters, the first step is the converstion of the width and the height to centimeters.

Each m has 100cm. So

The poster is 1.8 meters = 0.018 centimeters long and 1.25 meters = 0.0125 centimeters wide.

The area, in square centimers, is

`S = 0.018*0.0125 = 0.000225`

The area of the poster, in square centimers, is 0.000225 cm².
