What is the formula to find the perimeter of a rhombus?
All the 4 sides of a rhombus are equal, so 4 times the length of a side.
Area of rhombus if area and perimeter is given and if you have to find altitude?
Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
Do you add all of the sides that are given for perimeter?
Yes. For example, to find the perimeter of a square, add the length of the four sides.
How do you find the perimeter of trapezoid when two sides are given?
Find the other 2 sides and then add the 4 sides together.
How do you find the perimeter of a rhombus when area is given?
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.
