If you are asked to provide a set of two or more numeric answers, separate them with commas. For example, to provide the year that Sputnik (the first satellite to be sent into orbit around the Earth) was launched and the year humans first walked on the Moon, you would enter 1957,1969 in the answer box. A rectangle has a length of 5.50 m and a width of 12.0 m. What are the perimeter and area of this rectangle? Enter the perimeter and area numerically separated by a comma. The perimeter should be given in meters and the area in square meters. Do not enter the units; they are provided to the right of the answer box.

perimeter, area = 35.0,66.0 m, m2 (enter only '35.0,66.0')

When entering large numbers in the answer box, do not use commas. For example, enter 1276400‎ for the number 1,276,400. Do not enter 1,276,400‎. If you accidentally enter commas, you will receive feedback as a reminder. Answer the following question by typing the numeric answer into the answer box. What is the sum of 9260 and 3240?

sum = 12500
