Let the other diagonal be x:-
If: 0.5*x*12 = 54
Then: x = 54/6 => 9
The rhombus will consist of 4 right angles: base 4.5 cm and height 6 cm
Using Pythagoras: hypotenuses = 7.5 cm
Therefore perimeter: 4*7.5 = 30 cm

A square IS always a special kind of rhombus.
What is the area of a kite when perimeter is 56 and the diagonal is 12?
Area of a kite in square units = 0.5 times the product of its diagonals
What is the perimeter of a rhombus when the diagonals equal 30 and 40 inches?
Each side S = square root ( 152 + 202 ) = 25The perimeter will then be 4 x S = 100

What are all the names of all the quadrilateral with pictures?
Rectangle: A quadrilateral with 4 right angles, diagonals congruent/bisecting, and opposite sides congruent, BUT ADJACENT SIDES ARE NOT CONGRUENT. Rhobus: A quadrilateral with opposite congruent angles, but adjacent angles are Not congruent, perpendicular bisecting diagonals and 4 congruent sides. Square: A quadrilateral that is a rectangle and a square with 4 right angles, diagonals congruet/bisecting that ar perpendicular, and opposites sides congruent.

If a rhombus has diagonals of lengths 7cm and 12cm Using the Pythagorean theorem calculate the perimeter?
Perimeter: 4 times square root of (3.5^2+6^2) = 2 times square root of 193 in cm
What is the perimeter of a square with diagonal 12 centimeters?
The perimeter of a square with a diagonal of 12 centimeters is: 33.9 centimeters.In future, to find out the perimeter of a square when you only know it's diagonal, use Pythagoras or times the diagonal by 2.828427125.This number is irrational, and is like a pi for the diagonals of squares.I call it Tau.It is the relationship between the diagonal of all squares and there perimeter.
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.
How many diagonals does a square have?
It has 2 Diagonals!!!
What is the perimeter of a rhombus when one of its diagonals is greater than the other diagonal by 5 cm with an area of 150 square cm showing key aspects of work?
Let the diagonals be x+5 and x:- If: 0.5*(x+5)*x = 150 sq cm Then: x2+5x-300 = 0 Solving the above by means of the quadratic equation formula: x = +15 Therefore: diagonals are 15 cm and 20 cm The rhombus has 4 interior right angle triangles each having an hypotenuse Dimensions of their sides: 7.5 and 10 cm Using Pythagoras' theorem: 7.52+102 = 156.25 Its square root: 12.5 cm Thus: 4*12.5 = 50 cm which is the perimeter of the rhombus Note: area of any quadrilateral whose diagonals are perpendicular is 0.5*product of their diagonals
