L = .5W +9
L + W = 60 (substitute to solve a system)
W + .5W +9 = 60
-9 -9
1.5W = 51
W = 34
L = .5W + 9
L = .5 (34) + 9
Length = 26 cmThe width of the rectangle is 4 cm
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.
If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.
Perimeter of rectangle = 2 x (length + width) = 2 x (1.6 + 0.8) = 2 x 2.4 = 4.8 meters
width=9 length=18
The length is (18 centimeters) minus (the width)
30 ft
46 centimeters
77cm!
150 cm !
Perimeter of rectangle = 2 x (Length + Width) = 2 x (L + 18) or = (2L + 36) centimetres.

Another Answer:The length of the rectangle is 29 cm because 2*(29+23) = 104 cm which is the perimeter
