Question

Latoya has a rectangular poster that is 20 centimeters long and 15 centimeters wide. What is the area of the poster in square meters? Do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

Explanation:

The poster has the dimensions: 20cm x 15cm.

20cm x 15cm = 300cm^2

Our answer must be in meters, and

1cm^2 = 0.0001m^2

Therefore,

300cm^2 = 300 x 0.0001m^2

300cm^2 = 0.03m^2

Another way we could have found this is by converting the centimeters to meters before finding the area.

100cm = 1m

20cm/100cm = .2m

15cm/100cm = .15m

.2m x .15m = .03m^2

Your answer is 0.03m^2.
