The perimeter of a rectangular shape such as a poster is 2 x length + 2 x width.
In this example the perimeter = (2 x 3) + (2 x 6) = 6 + 12 = 18 feet
It is a rectangle and its perimeter is 12+12+6+6 = 36 feet

That rhombus has a perimeter of 18.88 feet.
22 feet. perimeter is the lenghth of all 4 sides of a square (box).
Assuming that the table is rectangular, the perimeter is 16 feet; 5 + 5 + 3 + 3
166 feet
If the given dimensions are that of a rectangle then perimeter is: 34 feet
80 feet
Perimeter = 2+3+2+3 10 feet
It is a rectangle and its perimeter is 12+12+6+6 = 36 feet

That rhombus has a perimeter of 18.88 feet.
22 feet. perimeter is the lenghth of all 4 sides of a square (box).

Assuming that the table is rectangular, the perimeter is 16 feet; 5 + 5 + 3 + 3
270 feet.
The diagonal is 10 feet. The one side is 8 feet and the other side is 6 feet (by Pythagoras 82 + 62 = 102)). The perimeter is thus 28 feet.
