The perimeter of a rectangle is double the (sum of length plus width).

Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.

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.

Add up (double the length) plus (double the width).

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.

If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length

The length of the rectangle is 18cm. The width of the rectangle is 9cm.

the perimeter will double. but the area should doubled to four

If you double its length and double its width and add those two amounts together you have the perimeter.

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

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

In the simplified format:Perimeter of a rectangle = (Length) + (Width) + (Length) + (Width)In the advanced format:Perimeter of a rectangle = 2 x (Length + Width)

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

you need length and width length multiply width = area length + length + width + width = perimeter

Length + length + width + width = perimeter. Length + width x 2 = perimeter

perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in

The perimeter of a rectangle with a length of 8.5 feet and a width of 4.5 feet is 26.

Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length

I think you mean the width is 6. The answer depends entirely on what the length of the rectangle is. For example, if it is a square, so that the length and width are both 6, the answer is 24. I the length is 10, the perimeter is 32. In general, just add the width (6) to the length and double the sum to get the perimeter.

The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)

If people say that "perimeter is the length times width" stop listening to them. They don't know what they are talking about.Length times width is the area, not the perimeter. For a square or rectangle, the perimeter is double the sum of the length and the width.

The perimeter of a rectangle is twice the sum of the width and length: perimeter = 2 x (4.6in + 12.1 in) = 33.4 in

To find the perimeter of a rectangle simply add the length and width then double your answer.

P=2L+2W Add double the length to double the width 30+17=47

perimeter = (2*length) + (2*width) length = 2*width so perimeter = (2*2*width) + 2*width = 6*width perimeter = 48 so you can figure out the width and length
