2 x (l + w)or 2l + 2w
The perimeter of a rectangle is found by the following formula: (Length x 2) + (Width x 2) or Length + Length + Width + Width.
(length) (times) (width) (times) (two) l x w x 2 = THE TOTAL PERIMETER OF THE SHAPE
s=side length P=perimeter P=4s
For a general rule for any object with four sides that have internal angles of 90 degrees just multiply the length by width.
area of parallelogram= base*height perimeter= 2(length+breadth)
Length times width.
Length x width
length times width
length x width= area ex if the length of the square was 10 and the width was 5, 10 x 5= 50units^2
P = 8s where s is the length of a side.
Area= Length x Width x Height
Measure it with a rule or find its perimeter and subtract the other 2 sides from it
