The answer depends on what information is given to you.
The are different formulae for its perimeter, area, lengths of diagonals, angle and these depend on what information is provided.

There is no specific "formula." If you want the area of a rhombus, that is just A = bh/2 or (1/2)xy where x and y are the lengths of the diagonals.
There is no "the" formula. The answer depends on what you are looking for: perimeter, length of side, diagonal, area, angles; and what information you have.For example, given the length of a side (s) and an angle (A), Area = s^2*sin(A).The question needs to be more precise in terms of what is required.
P = 4*a (a is side length) Area = p*q/2 (p=perimeter, q=diagonal
it is impossible for a diagonal of a rhombus to be the same length as its perimeter
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 are different formulae for its perimeter, area, lengths of diagonals, angle and these depend on what information is provided.
Its perimeter is the sum of its 4 sides Its area is 0.5 times the product of its diagonals

Area equals base times height. The perimeter is 4 times the length of one 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.
Units, because the perimeter is just the edge. The area is square units.
Perimeter = 29 cm so each side is 7.25 cm. The triangle formed by the diagonal and two sides has sides of 7.25, 7.25 and 11.8 cm so, using Heron's formula, its area is 24.9 square cm. Therefore, the area of the rhombus is twice that = 49.7 square cm.
With perimeter 10 and all sides equal fora rhombus, each side (base) is 10/4 = 2.5 inch Area = base times altitude = 2.5 x 12 = 30
