Using the formula above P= 2w + 2L, Find the value of the Width of the rectangle

Answer: 17
Step-by-step explanation: You take 47, multiply it by 2 and you should get 94. Subtract 128 and 94 which =34. Since the perimeter = 2 times the original width you divide that by 2 and get 17.
Step-by-step explanation:
[tex]P = 2w + 2l \\ P = 2(w + l) \\ 128 = 2(w + 47) \\ w + 47 = 64 \\ w = 17 \: cm[/tex]
