If the length of a rectangle is 8 cm more than 3 times its width and the perimeter is 64 cm what are the dimensions of the rectangle?
This is an algebra problem.
Let's call the length L and the width W
L = 3W + 8 is an equation describing the first part of the problem
2L + 2W = 64 is an equation describing the second part of the problem.
Now, lets substitute the (2L) in the second equation with twice the value of L in the first equation
2(3W + 8) + 2W = 64, and now we'll work out the contents of the brackets.
6W + 16 + 2W = 64, now add the values of W
8W + 16 = 64, now bring all the numeric values to the same side of the equation
8W = 64 - 16
8W = 48, now divide both sides by 8
W = 6
Now we can substitute 6 for W in the first equation
L = 3(6) + 8, now we'll work out the contents of the brackets
L = 18 + 8 now we'll add the numbers
L = 26
So now we have two values and we need to ensure that they add up to 64
2(26) + 2(6) = 52 + 12 = 64
So, the rectangle is 26 x 6

What is the perimeter of 9 by 13?
To find the perimeter of a rectangle, you use the formula (P = 2 \times (length + width)). For a rectangle with dimensions 9 and 13, the perimeter is (P = 2 \times (9 + 13) = 2 \times 22 = 44). Thus, the perimeter is 44 units.
A rectangle that is 12 cm in area and 16 in perimeter?
To find the dimensions of the rectangle, we need to set up equations based on the given area and perimeter. The area of a rectangle is length multiplied by width, so length times width equals 12 cm. The perimeter of a rectangle is given by the formula 2(length + width), which in this case equals 16 cm. By solving these two equations simultaneously, we can find the dimensions of the rectangle.
If the perimeter of a rectangle is twenty four inches find the dimensions if its length is three times the height.?
That would be 3 x 9 inches.
Perimeter of a rectangle?
2 times (length + width)
Area and perimeter of a rectangle?
Area is length times width, perimeter is twice the sum of length and breadth.
What is the perimeter of a rectangle if the length is 30m and the width is 20m?
The perimeter of a rectangle is calculated using the formula ( P = 2 \times (length + width) ). For a rectangle with a length of 30 meters and a width of 20 meters, the perimeter would be ( P = 2 \times (30 + 20) = 2 \times 50 = 100 ) meters. Thus, the perimeter of the rectangle is 100 meters.

What happens to the perimeter of a rectangle when you double one of its dimensions?
The perimeter of a rectangle is given by (2L plus 2W). If you double either the width or length dimension, then it is four times the original dimension, such as (4L plus 2W) or (2L plus 4W).
