To simply find the perimeter of a 3ft 8ft rectangle you say 2 times 8 which is 16
2 times 3 gives you 6 when add the 16 and the 6 you get 22
Oh, dude, the perimeter of a rectangle is just adding up all the sides, so for a 12ft by 8ft rectangle, you just do 12 + 12 + 8 + 8, which equals 40 feet. It's like measuring the sides of a fence but with math instead of a tape measure.
what is the perimeter of the rectangle
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
p(rectangle)=2*(L+B) =2*(5+3) =16 L=length , B=breath p(rectangle)=2*(L+B) =2*(5+3) =16 L=length , B=breath
Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.
