L = length
W = width
L = W + 7
and
Perimeter = 2*(W + L)
so
Perimeter = 2*(W + (W + 7)) = 2*(2W + 7) = 4W + 14

What is the expression of a perimeter of a rectangle if a rectangle has a width of n and a length of 2n?
The perimeter of any rectangle is twice the sum of the length and the width of the rectangle; in the present instance, 2(n + 2n) = 6n.
What is the best algebraic representation of the rectangles perimeter?
It is: 2(x+y) = perimeter whereas x is the width and y is the length of the rectangle
What is an expression for the perimeter of a rectangle with a length for l centimeters and a width of 18 centimeters?
Perimeter of rectangle = 2 x (Length + Width) = 2 x (L + 18) or = (2L + 36) centimetres.
What expression represents the perimeter of the rectangle 15 ft wide 25 ft length?
P=(L+W)x2 Where P = Perimeter, L=Length and W=Width.
What is an expression for the perimeter of a rectangle that has a length which is seven times its width?
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
What is the expression of a perimeter of a rectangle if a rectangle has a width of n and a length of 2n?
The perimeter of any rectangle is twice the sum of the length and the width of the rectangle; in the present instance, 2(n + 2n) = 6n.
What is the best algebraic representation of the rectangles perimeter?
It is: 2(x+y) = perimeter whereas x is the width and y is the length of the rectangle
What is an expression for the perimeter of a rectangle that has a length which is three times its width?
call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x
What is an expression for the perimeter of a rectangle with a length for l centimeters and a width of 18 centimeters?
Perimeter of rectangle = 2 x (Length + Width) = 2 x (L + 18) or = (2L + 36) centimetres.
What is the length of a rectangle that its perimeter is 30?
The perimeter of a rectangle is not sufficient to determine its length.
How do you simplify an expression for the perimeter and area of a rectangle?
Represent the length of the rectangle by L and the width by W. The perimeter = 2L + 2W = 2(L + W). The area = L x W.
What expression represents the perimeter of the rectangle 15 ft wide 25 ft length?
P=(L+W)x2 Where P = Perimeter, L=Length and W=Width.
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.
What is an expression for the perimeter of a rectangle that has a length which is seven times its width?
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
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.
The langth around a recrangle is called the?
The length round a rectangle is the perimeter.
What is the perimeter of a rectangle whose length is 5cm with a width of 6cm?
