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.

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.

The formula of the rectangle is multiplying the length and the width to get the area. You can add all the four sides so as to find the perimeter of the rectangle.

The perimeter of a rectangle is found by the following formula: (Length x 2) + (Width x 2) or Length + Length + Width + Width.

You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.

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).

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.

For a rectangle, P = 2L + 2W (L is length, W is width)

If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.

The perimeter of a rectangle is not sufficient to determine its length.

perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or 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)

Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.

It is impossible to find the perimeter without the width of the rectangle but if you want a formula it would be (43*2) + 2x. x representing the width

The perimeter of a rectangle is 42. Meters. The length of the rectangle is threemeter less than twice the width.Mar

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

The formula for the perimeter of a rectangle with length L and width W is P = 2*(L + W) In a square, the length and width are the same. So L = W And so A = 2*(L + L) = 2*(2L) = 4*L

for area you multiply length times width and for perimeter you add all of the sides together

The length of a rectangle is 8 inches. The width of the rectangle is 4 inches. What is the perimeter of the rectangle in inches?

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

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

the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle

The formula for perimeter is 2l+2w or 2*length + 2*width. This means that you multiply the length by two and multiply the width by two. Then, you add the two products together to find the perimeter.
