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

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 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.


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.


What is the perimeter of a rectangle whose width is x - 7 units and whose length is 3x 10 units?

The perimeter of a rectangle is calculated by adding up all the sides. In this case, the width is x - 7 units and the length is 3x + 10 units. Therefore, the perimeter would be P = 2(width) + 2(length). Substituting the given values, we get P = 2(x - 7) + 2(3x + 10) = 2x - 14 + 6x + 20 = 8x + 6 units.


What special name is given to a rectangle whose length and width are the same?

If a rectangle has its length equal to its width, then all four sides are of equal length and it is a square.

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


What is the length and width of a table top that is haped like a rectangle whose perimeter is 73.4inches and the length is 4.7 inches?

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

What is the perimeter of a rectangle whose length is 25 centimeter and whose width is 13 centimeter?

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
