+ Week Six: Problem 6. ) The figure below has a perimeter of 74 inches. What is the length of the missing side? a. ) 14 inches b. ) 8 inches c. ) 11 inches d. ) 15 inches e. ) 74 inches
+ Week Six: Solution 6. ) The figure below has a perimeter of 74 inches. What is the length of the missing side? a. ) 14 inches b. ) 8 inches c. ) 11 inches d. ) 15 inches e. ) 74 inches The missing side is 15 inches long. To find the perimeter, you would add each side. Since one side is missing, we add the sides and subtract from the total perimeter, or 74 inches. We also had to change the 1 ft 3 in and 1 ft 2 in into 15 and 14 inches to add and subtract the common measurements.

+ Week Eleven: Solution 11. ) Suzanne drew a rectangle with a perimeter of 12 inches. One side of the rectangle was 4 inches. What were the lengths of the other three sides? The other three sides were 4, 2, and 2 inches. I know this because rectangles have two sets of parallel sides. If one side was 4 inches, there must be another side with 4 inches. 4 + 4 = 8. If the total perimeter is 12 inches and we’ve already used 8, that means there are 4 inches left. The last two sides must then be 2 inches each, because they have to be equal.
