if the perimeter is 66in and the length is 3 all u have to do is this
3+3= 6
66-6=60
60/2=30
your width of one side of the rectangle is 30in

Using Pythagoras' theorem the length of the diagonal is 15 units
Perimeter, since it measures the distance around a shape. Area measures the interior. Or, more specifically, height by width, for example, 8x10 or 11x14 (inches). The perimeter for an 8x10 would be 2 times 8 plus 2 times 10, or 36 inches, but that would be insufficient to differentate an 8x10 frame from, say, a 6x12 frame (admittedly a rare size, but still possible.) So, while the common specification of a frame by height and width could be reduced to either perimeter or area, it is never done that way, precisely because important information is lost, the actual usable size of the frame.
The width of a rectangle is the shorter measurement and length is the longer. So in the case of the picture frame, 6 inches would be the width, and 10 inches would be the length.
6 in. by 8 in., 10 in. by 5 in., 12 in. by 4 in.
Queen size bed slats typically measure around 60 inches in width to fit the mattress, which is also 60 inches wide. The length of the slats usually matches the length of the bed frame, which is generally 80 inches for a queen size. Slats can vary slightly in length depending on the specific design of the bed frame, but they generally adhere to these standard dimensions.
It is 2*(9+5) = 2*14 = 28 inches.
The perimeter is 2 times the length plus 2 times the width.
The perimeter of a window refers to the total distance around the outer edges of the window frame. It is calculated by adding together the lengths of all four sides of the window. For a rectangular window, the perimeter can be determined using the formula: P = 2(length + width). Understanding the perimeter is important for tasks such as framing, installation, or calculating materials needed for window treatments.
17.5 inches
Length and side: 7 inches and 5 inches respectively
The perimeter is the total of all the sides added up, which is two lengths and two widths. We can write the equation 66 = 2w + 2ℓ where 66 is perimeter, w is width, and ℓ is length. We can also write equation ℓ = 3w because the length is three times greater than the width. We can replace ℓ with 3w in the first equation because the second equation tells us they are the same thing: 66 = 2w + 2*(3w) Now we have an equation with one variable, so we can solve for that variable (w): 66 = 2w + 2*(3w) 66 = 2w + 6w 66 = 8w Divide both sides by 8: 8.25 = w The width is 6.6. We can plug that 6.6 into the equation ℓ = 3w to find the length: ℓ = 3*8.25 ℓ = 24.75 The length is 24.75. So the width is 8.25 and the length is 24.75.
Using Pythagoras' theorem the length of the diagonal is 15 units
It has a full perimeter frame.
If the length of each side of a rectangular picture frame needs to be 15 in and you only have 48 in of wood, use the following inequality to solve. 2l + 2w = p, in this case 2(15) + 2w <=48, so 2w <=18. The width of your fram must be 9 inches or less.
To create a frame measuring 3 feet by 4 feet with a diagonal, you will need to calculate the perimeter and add the diagonal length. The perimeter of the rectangle is 2(3 + 4) = 14 feet. The diagonal can be calculated using the Pythagorean theorem: √(3² + 4²) = 5 feet. Therefore, the total length needed is 14 + 5 = 19 feet. Since each board is 8 feet long, you will need 3 boards (2 for the perimeter and 1 for the diagonal).
Perimeter = 100 inches Area = 600 square inches
For any perimeter, the rectangle with the greatest area is a square.For a 16-inch perimeter, the greatest rectangular area is 16 square inches,inside a square with 4-inch sides.But if you don't necessarily need straight sides, then you can squeeze more areainside the same perimeter with a circle. A circle with a 16-inch circumference has anarea of 20.372 square inches.
