If x = 7 units, y = 3 units, and h = 9 units, find the area of the trapezoid shown above using decomposition.
Unfortunately, I cannot see the trapezoid you are referring to as this is a text-based platform. However, I can provide you with the formula for the area of a trapezoid and how to use decomposition to find the area.
The formula for the area of a trapezoid is:
A = (b1 + b2) / 2 * h
where b1 and b2 are the lengths of the parallel sides of the trapezoid and h is the height.
To use decomposition to find the area of a trapezoid, you can divide it into a rectangle and two right triangles. The height of the rectangle is the same as the height of the trapezoid, and the base of the rectangle is the average of the lengths of the parallel sides of the trapezoid. The two right triangles are congruent and have a base equal to half the difference between the lengths of the parallel sides of the trapezoid and a height equal to the height of the trapezoid.
Once you have found the area of each of these shapes, you can add them together to get the total area of the trapezoid.
I hope this helps!
