Question

Kira has a rectangular poster that is 12 centimeters long and 10 centimeters wide. What is the area of the poster in square meters?

Answer 1

The area of the poster is 0.012 square meters.

Explanation:

Finding the area of the poster:

The formula for the area of a rectangle is given by:

A = LW, where,

• A is the area in square units,
• L is the length,

• and W is the width.

Converting the length and width to meters:

There are 100 centimeters in a meter.

Thus, we can convert the length and width to meters by dividing both numbers by 100:

Finding the length in meters:

Length in meters = 12 / 100

Length in meters = 0.12

Thus, the length is 0.12 meters.

Finding the width in meters:

Width in meters = 10 / 100

Width in meters = 0.1

Thus, the width is 0.1 meters.

Finding the area:

Since the length is 0.12 meters and the width is 0.1 meters, we can find the area of the poster by substituting 0.12 for L and 0.1 for W in the formula for the area of a rectangle:

A = 0.12 * 0.1

A = 0.012

Thus, the area of the rectangular poster is 0.012 square meters.
