24 cm
Well, perimeter is L+W times 2.
2(L+W)=P
If P is 64 and L is 3W, then:
64=2(3W+W)=2(4W)=8W
8W=64
W=8
L=3W
L=3(8)=24

What is the area of a rectangle whose perimeter is 136?
If the only information that you have is ... A) the figure is a rectangle, and B) the perimeter ... then you cannot calculate the area. The area of a rectangle is the length multiplied by the height., The perimeter is twice the length plus twice the height. So, a rectangle with a length of 9 units and a height of 1 until will have a perimeter of 20 units and an area of 9 square units. Another rectangle with a length of 6 units and a height of 4 units will also have a perimeter of 20 units, but it will have an area of 24 square units. To be able to calculate the area from the perimeter you need to know one of two additional things - either one of the measurements, or the ratio of the height to the length.
NAME A geometric shape whose perimeter has infinite length?
Fractal,
What is the length and width of a traffic sign whose perimeter is 74 inches and length is 9 inches longer?
Length + width = half of perimeter = 37 in. 37 - 9 = 28, half of 28 = 14 which is the width, and the length is 23
What is the length of the side of a square whose perimeter is 160 cm?
The perimeter of a square = side+side+side+side if 160=4xside then the side equals 40
What is the perimiter of a regular hexagon whose sides measure 7 cm?
A regular hexagon has 6 sides of equal length ("hex" means six). The perimeter is just the length of all the sides added up. So, Perimeter = 6 x 7 = 42 cm
What is the perimeter of a rectangle whose length is 5cm with a width of 6cm?
The perimeter of a rectangle whose length is 5cm wit a width of 6cm is 22cm
What are the dimensions of a rectangle whose perimeter is cm if its length is 2 cm more than thrice its width?
You forgot to put in the length of the rectangle's perimeter.
What is the perimeter of a rectangle whose length is 18 cm and breadth is 10 cm?
56 cm Perimeter of a rectangle is given by 2(length + breadth). So, perimeter of given rectangle = 2(18 + 10) = 56

Rectangle whose perimeter is larger than area?
Perimeter is a unit of length. Area is a unit of area. The two units are not directly convertible.However, the area of a rectangle is length times width, and the perimeter is two times length plus two times width. Given constant perimeter, a square has maximum area, while a very thin rectangle has nearly zero area. (In calculus terms, the limit of the area as length or width goes to zero is zero.)Depending on how you want to name your units, you can always find a rectangle whose perimeter is "larger" than area, but this is a numerical trick that is not valid in any school of thought of mathematics that I know.
How to find the breadth of a rectangle whose perimeter is 140m and length is 40m?
360
What is the width of a rectangle whose length is 4ft and perimeter is at most 20ft?
6 feet
What perimeter of a rectangle whose length is 5 feet and whose width is 3.5 feet?
Perimeter = 5+5+3.5+3.5 = 17 feet
What is the perimeter of a garden whose length is 2 times the width and perimeter is 144 - what is the length?
72
What is the perimeter in feet of a rectangle whose length is twice its width and whose width is 9 feet?
If the width is 9' and the length is twice that, the length is 18'; the perimeter is twice the length plus twice the width, which is 36' + 18' = 54 feet.
What is the perimeter of a rectangle whose with is 6?
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.
What is the perimeter of a rectangle whose dimension are the length is 24.6 the width is 12.2?
Perimeter = 2*(Length + Width) = 2*(24.6 + 12.2) = 2*36.8 = 73.6 units
