12 meters.

9 meters.

Perimeter of this rectangle is equal to 12 meters plus 9 meters plus 12 meters plus 9 meters which is equal to 42.

Unit of perimeter is the same as the unit of length.

12 plus 12 plus 9 plus 9.

Is equal to 2 into 12 plus 2 into 9.

Is equal to 2 into length plus breadth.

Therefore, perimeter of a rectangle.

Is equal to 2 into length plus breadth.
