12*2+20*2 = 64 mm
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!
The perimeter of the rectangle is 42 units
The length round a rectangle is the perimeter.
Some are 12mm and others 14mm depends on he model..
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
The perimeter of a rectangle is not sufficient to determine its length.
The perimeter of the rectangle is the sum of its 4 sides.
perimeter of a rectangle is 20 on each side
the perimeter of a rectangle is calculated by : 2*(l+b)
That depends. The perimeter of a rectangle equals the all the sides added together! The perimeter of a rectangle is the distance around it. The formula for finding the perimeter of a rectangle is: P = 2L + 2W (the length x 2 added to the width x 2). Example: A 5x10 rectangle has a perimeter of 30: (5x2 + 10x2 = 30)
