If it is a square, divide 12 mm by 4. Obviously it is a 3 mm per side. You don't have enough info for a rectangle or other shape unless it is a triangle which would be 4 mm for an equilateral triangle.
Area = side x side; perimeter = side x 4.
Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
The same way you find the perimeter of a rectangle, add the side lengths
Find out what 1 side is and multiply by 3 to find perimeter
Not exactly. If I know the side lengths, I can still find the perimeter
Well, isn't that just lovely? If the side length of a square is 12mm, then all four sides are equal in length. So, to find the perimeter, you simply add up all the sides, which would be 12mm + 12mm + 12mm + 12mm, giving you a total perimeter of 48mm. Just imagine all the happy little measurements coming together to create a beautiful square!
52mm
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
Area = side x side; perimeter = side x 4.
Find the distance of each side and add to find the total perimeter.
Divide the perimeter by eight.
Perimeter=find each perimeter of each side of the box then add them all up area=find each are of each side of the box then add them all up
Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
find the perimeter of a square that has 12 m side
The same way you find the perimeter of a rectangle, add the side lengths
