Help.
12 meters.
9 meters.
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.
Perimeter of a square.
