Hexagon
To find the perimeter of a rectangle you simply add up the sides. Easy. because there are 2 sets of identical sides, u can multiply each by 2 and add. 16 x 2 = 32 8 x 2 = 16 and add 32 + 16 to get your answer
Add up all the sides of the rectangle.
You add up all of the sides of the rectangle.
You can`t be sure of the individual sides. A one inch by sixteen inch rectangle, an eight by two inch rectangle, a four inch by four inch rectangle all have the same area (16 square inches) but the first rectangle`s sides add up to 34, the second rectangle`s sides add up to 20, the third rectangle`s sides add up to 16

To calculate the perimeter of a rectangle, you need to add together the length of each side of the rectangle. For a rectangle that is 11cm x 4cm, you would add these numbers together, then multiply it by 2 (this is because there are two sides that are 11cm and two sides that are 4cm). Thus: (11+4) x 2 = 30cm.
Add together all the sides... i.e. Area(rectangle) = 2(l+w)
Add together the 4 sides
add the lengths of all the sides
