Jessica has a rectangular poster. the poster is 1.8 meters long and 1.5 meters wide. what is the area of the poster in square centimeters?

You have to multiply length times width. In this case, the length is 1.8 meters. and the width is 1.5 meters. That would give you a total of 2.7 meters square. They are telling to you to put the answer in centimeters, so you have to change the meters to centimeters, 1 meters = 100 centimeters, so you have to multiply 2.7*100 which would give you an answer of 270 square centimeters. YOU'RE WELCOME :)
