You would also double the perimeter.

Q: If you double the length and width how does that effect the perimeter?

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

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

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

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

Yes it will. How thick are you?

It's double the sum of (length + width).

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

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 will double. but the area should doubled to four

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

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

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

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

width = (perimeter-2*length)/2

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