Answer:

w = 3.2 cm

Step-by-step explanation:

Perimeter of a rectangle = 2(l + w)

Given values:

  • p = 39.2 cm
  • l = 16.4 cm

Substitute the given values into the formula and solve:

39.2 = 2(16.4 + w)

39.2 = 2(16.4 + w)

39.2 = 32.8 + 2w

39.2 - 32.8 = 32.8 - 32.8 + 2w

6.4 = 2w

6.4 / 2 = 2w / 2

3.2 = w

Check your work:

39.2 = 2(16.4 + 3.2)

39.2 = 2(19.6)

39.2 = 39.2 ✅

Final answer: w = 3.2 cm

Hope this helps!
