  • A
  • B148 cm
  • C
  • D296 cm

Step-by-Step Solution

Distance around the edge = perimeter = cm. is the area and 148 cm covers only two sides. Watch the unit too: a distance is measured in cm, never , so "" is wrong even though the number is right.
Answer: D) 296 cm

Key idea: Perimeter — the journey around

Imagine an ant walking around the edge of a shape and returning to where it started. The total distance it walks is the perimeter. For any closed shape: **add up every side**. Order doesn't matter; just include each side once.

For a triangle with sides 3, 4, 5: perimeter = 3 + 4 + 5 = 12. For an irregular shape: add every edge.
