52mm
To determine how much bigger 14mm is than 12mm, subtract 12mm from 14mm. This calculation shows that 14mm is 2mm bigger than 12mm.
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
Some are 12mm and others 14mm depends on he model..
The length round a rectangle is the perimeter.
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 !
perimeter of a rectangle is 20 on each side
The perimeter of the rectangle is the sum of its 4 sides.
the perimeter of a rectangle is calculated by : 2*(l+b)
The perimeter of a rectangle is not sufficient to determine its length.
