A "right angle" doesn't have a perimeter. From the rest of the question,

we suspect that you might have meant to say a "right triangle", but that's

just a guess.

The perimeter of any triangle is the sum of the lengths of all three sides.

In a right triangle, the length of the longest side is the square root of the

sum of the squares of the two short sides.

We're sure you can handle it from here.

Q: How do you find the perimeter of a right angle when the length is 8 and the width is 8?

Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.

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

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

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

Perimeter = 2 lengths + 2 widths 1/2 perimeter = length + width Length = 1/2 perimeter - width Area = length x width That's (1/2 perimeter - width) x (width) .

width = (perimeter-2*length)/2

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

The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.

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.

Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter

The perimeter is the total distance around - width + width+ length + length.
