Perimeter of Rectangle = 2(length + width) =2(45+30) =150 cm
The perimeter of a triangle is the sum of its 3 sides.
20 and a half cm.
half of 54.5 inches in cm? 27.25 inches in cm? 1 cm = 2.54 inches; ? cm = 27.25 inches; cross multiply 27.25incm=?2.54incm; 27.25incm/2.54in=?cm ~10.73 cm
5.47 m or 547 cm
The sum of 3.8 cm and 17.3 cm is the measurement half around the rectangle.Double that and you've got your answer.(3.8+17.3) times 221.1 x 2= 42.2
14.9 cm.
