How do you find the length and width of a rectangle when the perimeter and area are given?
it cannot be solved
------------------------------------------------
Actually, you can. Suppose, as an example, that the rectangle's area and perimeter are 6 and 10 respectively. Let therectangles length and width be represented by L and W respectively. Then
LW = 6 (a) and
2 ( L + W ) = 10 (b)
Let me rearrange (b) to obtain an expression for W: W = 5 - L.
Now let me substitute this expression for W in (a): L ( 5 - L ) = 6.
This is a quadratic equation that one can solve for L. Let me do it by factoring,
L^2 - 5 L + 6 = 0 = ( L - 2 ) ( L - 3 )
This implies that L=2 or L=3. With L=2, W=3; with L=3, W=2. Put simply the rectangle's length and width are 3 and 2 respectively.

Find the perimemter of a rectangle with length 15 meters and width 10 meters?
The perimeter of a rectangle is given by:P = 2l + 2w, where P is the perimeter of the rectangle, l is the length of the rectangle, and w is the width of the rectangle.P = 2(15) + 2(10) = 50 meters.
The perimeter of a rectangle is 24 inches. And its length is 3 times its width. What are the length and the width of the rectangle?
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.

What is the width of a rectangle if the perimeter is 75m and the length is 10m?
The width of the rectangle would be 32.5 meters.
What is the formula to find the length of a rectangle when the perimeter and width is already given?
Length = (Perimeter - twice width) / 2
How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
How can you calculate the length of a rectangle if the perimeter and the width are given?
Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.
How do you find the length and width of rectangle when given the perimeter but not the width or length?
by appying 2l+2w
How do you find the perimeter of a rectangle given the length and width?
Perimeter = 2*(L + W).
What is a perimeter of a recangular?
Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.
How can you get the width when you have the perimeter and the length?
If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length

The perimeter of a rectangle whose length is 5cm wit a width of 6cm is 22cm
How do you find the optimal area of a rectangle given its perimeter?
Multiply length by width
The width of a rectangle is one half its length The perimeter of the rectangle is 54cm What are the width and length of the rectangle?
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
The length of a rectangle is twice its width If the perimeter of the rectangle is 54y find its area?
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
How do you find the width of a rectangle when the length and perimeter is given?
You multiply the length by 2 (because there are two sides of the rectangle that have that measure). You then subtract that number from the perimeter. The number you will be left with is twice the width, so you divide that by two and you get the width of the rectangle.
