The formula for the perimeter of a rectangle is: p = 2(l + w) In other words, just add all four sides. You can't calculate the perimeter of the rectangle if you know only the length.
When you think about it for a while, they're really NOT different. The rectangle formula needs a bit more detail, because its sides don't all have the same length, so its length and its width have to be handled separately. But the rectangle formula works perfectly well if you use it to find the perimeter of a square.
The perimeter of any rectangle is [ 2 x (length + width) ]. Since the length and width of a square are equal, the perimeter of a square is also [ 2 x (side + side) ] = (4 x side).
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
Length = (Perimeter - twice width) / 2
The perimeter of a rectangle with dimensions of 8 X 6 is 28 units.To find the perimeter, you use the formula: 2l+2w, where l is the length and w is the width.In your case, the formula would read: 2(8) + 2(6) = 16 + 12 = 28
Square is a special case of a rectangle and the same formula may be used to find the perimeter
2(length + height)= perimeter
no
The formula for finding the perimiter of a rectangle is add up all of its sides
yes
The formula for the perimeter of a rectangle is: p = 2(l + w) In other words, just add all four sides. You can't calculate the perimeter of the rectangle if you know only the length.
P=2w+2l
2 x base + 2 x height= perimeter
I think so

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)
