What is the actual perimeter of this roof section?   m

On a roof plan, a cable route measures 7.5 cm from the panel array to the equipment cabinet. The scale is 1 cm represents 1.2 m. The team adds 2 m to the actual route length for connections.

How much cable should the team plan for altogether?   m

3.
A project rule requires a clear gap of at least 1 m beside a panel array. The gap measures 0.75 cm on a plan where 1 cm represents 1.2 m. Which statement is correct?
  • A. The gap is 1.6 m, so it meets the rule.
  • B. The gap is 0.625 m, so it fails the rule.
  • C. The gap is 0.9 m, so it fails the rule.
  • D. The gap is 1.95 m, so it meets the rule.
