You forgot to put in the length of the rectangle's perimeter.

6 feet

Perimeter = 5+5+3.5+3.5 = 17 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.

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.

Perimeter = 2*(Length + Width) = 2*(24.6 + 12.2) = 2*36.8 = 73.6 units

that's easy.....it's 1 ;)

Length + width = half of perimeter ie 36.7 in. If length is 4.7 in then width is 32 in.

The perimeter of a rectangle is equal to twice the length plus twice the width, so P = 2l + 2w P = (2x25) + (2x13) P = 50 + 26 P = 76 centimeters

Perimeter equals the sum of all sides. Therefore 7+7+6+6=26

Let the length be x+5 and the width be x:- Perimeter = 2*(x+5+x) or 4x+10

yo brotha!

Think about two numbers whose multiplication is 9 or simply think about the factors of 9. Factors of 9 are 3x3 Now see perimeter of rectangle is 2 times sum of length and breadth. Perimeter of rectangle is 4 times side. 2 and 4 are of the factors of 9. So the figure cannot be rectangle or square. Perimeter of triangle= Sum of all sides 9 = 1+3+5 =9 Hence it is possible to have a triangle with perimeter 9cm as there are various numbers whose addition could be 9. So the figure could be triangle.

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.

They are tiles whose length is the same as their breadth.

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.

80cm.

A rectangle with width 4 can have any length!

72

Yes. Any rectangle whose length = (4 x width) divided by (width - 4) .

First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.

you want to get rid of the x first so you 7 from both sides.

The area of rectangle is : 152.0
