let x = length and let y = width. 52=2x+2y. x=2y-4. Use substitution:
52=2(2y-4)+2y. Simplify, and you get y=10=width.
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
divide perimeter by 6.

Twice the (width plus length)
If the perimeter is 84 feet and the length is twice the width, then the length will be 28 feet and the width will be 14 feet.
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
divide perimeter by 6.
Width = 16 feet Length = 38 feet
14 feet (14+14+28+28 = 84)
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.

A farmer wants to fence a rectangular garden whose perimeter is 60 yards. The length of the garden exceeds twice the width by 6 yards. What are the length and width of the garden?
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.
Length = (Perimeter - twice width) / 2
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
12 meters
