Area equals base times height. The perimeter is 4 times the length of one side.
Perimeter of a rhombus = 4 x (length of one side)(Notice how closely the formula resemblesthe one for the perimeter of a square.)
Four times the side.
There is no relationship between the perimeter and the area of a rhombus. Take a rhombus with all 4 sides = 2 units. Therefore the perimeter is 8 units. There are an infinite number of possible areas for this rhombus. The largest possible area will be when the rhombus approaches the shape of a square = 4 square units. The smallest area will be when the one diagonal approaches 0 units and the other diagonal approaches 4 units (squashed almost flat). So two very extreme areas can have the same perimeter, including all those areas in-between.
The perimeter of a rhombus is equal to 4 times the length of one side, so for a rhombus-shaped highway sign with a 20-centimeter side, the perimeter would be 4 x 20 = 80 centimeters.
60 units
The length of one diagonal is not sufficient to determine its sides and so its perimeter.
Each side of the rhombus will have a length of 105/4 = 26.25 dm
Rhombus is an equilateral four sided form. If one side is 6, the perimeter is 4 x 6 = 24. The altitude makes no difference.
A rhombus has four sides that are equal in length, so the perimeter can be found by multiplying the length of one side by four. Therefore, a rhombus highway sign with a 20 centimeter side has a perimeter of 80 centimeters.
Unless it is a rhombus (or square) you cannot.
142.4 just multiply 35.6 by 4 because a rhombus has 4 equal sides.
