The perimeter of a rectangle is 2length +2 width. the width is x the length is x+4. Plug into the equation 2(x)+2 (x+4)=20 2x+2x+8=20 4x=12 x=3 The width is 3 the length is 7 (3+4) Area is length times width. 3(7)= 21. the area is 21 centimeters
Length = (Perimeter - twice width) / 2
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
108 feet is the perimeter of a rectangle with a length of 50 feet and a width of 4 feet.
The length is (18 centimeters) minus (the width)
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
