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 :)
