The perimeter of a rectangle is 48 cm. The length is 6 cm less than twice the width. Which system would model this
situation, and what are the length and the width?
A 21+ 2w = 48
1 + 2w = 6
Solution: (9,6)
B. 21 +2w = 48
21+w=-6
Solution: (-32, 56)
C. + w = 48
1-2w = -6
Solution: (18,6)
D. 21 + 2w = 48
1-2w = -6
Solution: (14, 10)
