What formula expresses the perimeter of a rectangle in terms of its length?

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.


Formula of a rectangle?

There is no formula for a rectangle. There are formula for calculating its area, perimeter or length of diagonals from its sides, or it is possible to calculate the length of one pair of sides given the other sides and the area or perimeter, or the two lots of sides given area and perimeter and so on.

What is the formula for the perimeter of a square and rectangle?

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).


What is the peremiter of a rectangle?

The formula for perimeter of a rectangle is: P=2L+2W where L is the length and W is the width of the rectangle.


What is a perimeter of a rectangle?

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)


Explain why the formula for the perimeter of a rectangle and the formula for the perimeter of a square are different?

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.


Formula of rectangle?

Area=length x width Perimeter= 2l+2w


What is the difference between perimeter and area of polygon?
