It is: 841 square mm
It's possible for the digit to be smaller. A square with 3 feet on each side will have a 9 square foot area and a 12 foot perimeter. It's pointless to compare area and perimeter. They have different units.
If the shape is a triangle, then the area is approx 36.7 square mm.
Area = pi*262 = 676*pi square mm
21mm x 21mm = 441 square millimeters
If the perimeter of a square is 40 mm the area is: 100 mm2
It is: 841 square mm
The area of square is : 1936.0
Its width workks out as 64.5 mm and so area is: 64.5*78.3 = 5050.35 square mm
The formula for what? Its perimeter, area, diagonal, etc.
80 mm
It works out as: 35 cm or 350 mm
It is: 22.9*40.4 = 925.16 square mm
The area of square is : 576.0
Since a square has four sides, just multiply the side length by four: 12mm x 4 = 48 mm
24 divided by 4 sides is 6mm 6 times 6 is 36 36 mm
The perimeter of a square with a diagonal length of 24 square root 2 millimeters (33.94 mm) is: 96 mm
