What is the area of a rhombus when one of its diagonals is 11.8 cm in length and has a perimeter of 29 cm showing work and answer?

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.

What is the formula for perimeter of rhombus?
It depends on what information you have: the length of a side, or the lengths of the diagonals, or a diagonal and an angle. Each of these will give rise to a different formula.
What is the area of a rhombus with a perimeter diagonal?
it is impossible for a diagonal of a rhombus to be the same length as its perimeter
Why do the diagonals of a rhombus not have to be the same length?
The sides of a rhombus must all be the same length, but the angles do not need to be the same. The result is a diamond shape where the diagonals can be two different lengths.
The perimeter of a rhombus is 64 inches what is the length of each side of the rhombus?
16
What is the ratio of the length of diagonals of a rhombus?
They are the same length, so 1:1 * * * * * In fact that is the one ratio they cannot be. A rhombus with equal diagonals is a square. The ratio of the lengths can have any other positive value.
Is the diagonals of rhombus congruent?
"Congruent" isn't used to describe the diagonals of a rhombus. However, all four sides of a rhombus are congruent - they are all the same length.The diagonals of a rhombus are perpendicular to each other. They are not the same length - if the diagonals were the same length, then you would have a square.
Does a rhombus have equal length?
The answer depends on which aspect of a rhombus. Its sides are of equal length but its diagonals are NOT!

What is the relationship between diagonals on a rhombus?
Not in general. The diagonals of a rectangle are equal length. A rhombus that is also a rectangle would be a square.
Why do the diagonals of a rhombus not have to be the same length?
The sides of a rhombus must all be the same length, but the angles do not need to be the same. The result is a diamond shape where the diagonals can be two different lengths.
The diagonals of the rhombus are in the ratio 3 4 the perimeter of the rhombus is 40cm find the lengths of the sides and of the diagonals?
The length of the sides of the rhombus are 10cm, as a rhombus has equal sides. since the diagonals of a rhombus are perpendicular, ratio of side of rhombus to 1/2 a diagonal to 1/2 of another diagonal is 5:4:3 (pythagorean thriple), hence ratio of side of rhombus to 1 diagonal to another diagonal is 5:8:6. since 5 units = 10cm 8 units = 16cm 6 units = 12cm and there are your diagonals.
Which quadrilateral has All sides are the same length the diagonals are not equal in length?
rhombus
Are the diagonals of a rhombus perpendicular and bisect each other?
Yes, they are perpendicular and intersect at their midpoints. The difference between diagonals in a rhombus as opposed to a rectangle or square is that the diagonals are not of equal length.
What can you find about the diagonals of a rhombus?
The diagonals are not equal in length but thet bisect each other at 90 degrees
The perimeter of a rhombus is 64 inches what is the length of each side of the rhombus?
16
What is a parallelogram with diagonals of different length intersecting at right angles?
A rhombus.
