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
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 .
x=width x+25=length 4x+50=130 4x=80 x=20 width is 20 length is 45
The rectangle is in fact a square with 4 equal sides of 5 units in length.

Let the width be x: 2(length+width) = perimeter 2(20+x) = 50 40+2x = 50 2x = 50 -40 2x = 10 x = 5 centimeters Check: 5+5+20+20 = 50 centimeters

The perimeter of a rectangle measuring 20x45 centimeters is (2*20) + (2*45) = 40 + 90 = 130 cm
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
A 6 by 4 rectangle will have a perimeter of 20 units

Perimeter of rectangle: 2*(20+15) = 70m
Perimeter = 20+8+20+8 = 56 cm.....
a rectangle has a perimeter of 72m. If the length is 20 m longer than the width find its dimensions?
