If x = 3 units, y = 6 units, and h = 6 units, find the area of the rhombus shown above using decomposition.
To find the area of the rhombus, we can split it into two triangles using one of the diagonals as shown below:
x
/ \
/ \
y _______ h
\ /
\ /
x
Now we can find the area of each triangle and then add them together to get the total area of the rhombus.
Area of first triangle = (1/2)*(x)*h = (1/2)*(3)*(6) = 9 square units
Area of second triangle = (1/2)*(x)*y = (1/2)*(3)*(6) = 9 square units
Total area of the rhombus = 9 + 9 = 18 square units
Therefore, the area of the rhombus is 18 square units.
its not 18
I apologize for the mistake. Let's reevaluate the calculation.
Since the diagonals of a rhombus bisect each other at right angles, we can use the formula for the area of a rhombus which is A = (d1 * d2) / 2, where d1 and d2 are the lengths of the two diagonals.
In this case, let's say d1 is the diagonal that is x units and y units, and d2 is the diagonal that is x units and h units.
d1 = √(x^2 + y^2) = √(3^2 + 6^2) = √(9 + 36) = √45 units
d2 = √(x^2 + h^2) = √(3^2 + 6^2) = √(9 + 36) = √45 units
Area of the rhombus = (d1 * d2) / 2 = ( √45 * √45 ) / 2 = ( 45 ) / 2 = 22.5 square units
Therefore, the correct area of the rhombus is 22.5 square units.
its not 22.5
I apologize for the confusion. Let's try to find the correct area of the rhombus using the decomposition method.
Given:
x = 3 units
y = 6 units
h = 6 units
We will decompose the rhombus into two triangles by drawing a diagonal:
x
/ \
/ \
y ____ h
\ /
\ /
x
We can see that each triangle has a base of x units and a height of h/2 units (since the height is bisected by the diagonal).
Area of each triangle = (1/2) * base * height = (1/2) * x * (h/2) = (1/2) * 3 * 3 = 4.5 square units
Since the rhombus is made up of two congruent triangles, we can find the total area by adding the areas of the two triangles:
Total area = 2 * (Area of each triangle) = 2 * 4.5 = 9 square units
Therefore, the correct area of the rhombus is 9 square units. Thank you for your patience.

We can see that each triangle has a base of x units and a height of h units.
Area of each triangle = (1/2) * base * height = (1/2) * x * h = (1/2) * 3 * 6 = 9 square units
Since the rhombus is made up of two congruent triangles, we can find the total area by adding the areas of the two triangles:
Total area = 2 * (Area of each triangle) = 2 * 9 = 18 square units
Therefore, the correct area of the rhombus is 18 square units. Thank you for your patience and I appreciate your understanding.
