6cm. The perimeter of the rectangle has to add to 20. 4+4+6+6=20 Hope this helps ;-)
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides of length 20m and two sides of length 15m. Therefore, the perimeter would be 2(20m) + 2(15m) = 40m + 30m = 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
6cm. The perimeter of the rectangle has to add to 20. 4+4+6+6=20 Hope this helps ;-)
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

The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides of length 20m and two sides of length 15m. Therefore, the perimeter would be 2(20m) + 2(15m) = 40m + 30m = 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?
