rectangle. Use the formula P = 2L - 2W to set up and equation and solve for the width.

Answer:

9 cm

Step-by-step explanation:

L = 5+3W

P = 82

=> P = 2L + 2W

82 = 2(5+3W) +2W

82 = 10+6W+2W

82 = 10+8W

8W = 82-10

8W = 72

W = 72/8

W = 9

so, the width = 9 cm

☆Answer :

  • L = 5 + 3W
  • p = 82

p = 2L - 2W

82 = 2(5 + 3W) - 2W

82 = 10 + 16W - 2W

82 - 10 = 14W

72 = 14W

W [tex]\approx[/tex] 5.14cm
