Answer:

(a) 34 cm

Explanation:

The formula for perimeter of a rectangle is

P = 2l + 2w, where

  • P is the perimeter,
  • l is the length,
  • and w is the width.

Thus, we can plug in 12 for l and 5 for w in the perimeter formula and simplify to find the perimeter of the rectangle:

P = 2(12) + 2(5)

P = 24 + 10

P = 34

Thus, the perimeter of a rectangle with a length of 12 cm and a width of 5 cm is 34 cm.
