6cm. The perimeter of the rectangle has to add to 20. 4+4+6+6=20 Hope this helps ;-)

Perimeter of rectangle: 2*(20+15) = 70m

x=width x+25=length 4x+50=130 4x=80 x=20 width is 20 length is 45

The perimeter and area don't depend on each other. Knowing one doesn't tell you the other. -- A circle with perimeter (circumference) of 20 cm has area of 31.83 cm2. -- A square with perimeter of 20 cm has area of 25 cm2 . -- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2 . -- A (8 x 2) rectangle has perimeter of 20 cm and area of 16 cm2 . -- A (7 x 3) rectangle has perimeter of 20 cm and area of 21 cm2 . -- A (6 x 4) rectangle has perimeter of 20 cm and area of 24 cm2 .

The rectangle is in fact a square with 4 equal sides of 5 units in length.
