Millimeters, inches, light-years, miles, it's all the same: Measure all four sides and add their lengths together. That's what "perimeter" means.
For some figures there really is a formula. For example, since a square or a rhombus has all four sides the same length, you can just measure one of them and multiply by 4. But the sides of a trapezoid (not "TARPezoid") don't have any particular relationship in terms of length.
The perimeter is 60 mm
2(length + height)= perimeter
Square is a special case of a rectangle and the same formula may be used to find the perimeter
The perimeter of a pentagon is the sum of its 5 sides
Perimeter = sum of the lengths of the sides.
26cm
6.2mm
The perimeter is 60 mm
If it's a regular octagon, the perimeter is 8 times the length of one side.
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
The formula for the perimeter of a square is P equals 4 times a. 'P' represents the perimeter, and 'a' represents a side of the square.
Millimeters ARE thousandths of meters!
171 mm
(2) Length + (2) Width = Perimeter
2(length + height)= perimeter
The perimeter of a square with a diagonal length of 24 square root 2 millimeters (33.94 mm) is: 96 mm
Perimeter of a rhombus = 4 x (length of one side)(Notice how closely the formula resemblesthe one for the perimeter of a square.)
