Solution
The problem statement translates to:
- In the given diagram, is a parallelogram. , and intersects and at points and respectively. Given and , find the area of the parallelogram .
To solve this problem, we will follow these steps:
- Identify the relationships: Given , triangle is a right triangle with as the height and as the base.
- Calculate area of : The area of a triangle is given by . Here, and .
- Find : Using the given and knowing that is the perpendicular distance from to line , we realize that because both are heights from the same vertex to a parallel side (by the properties of a parallelogram).
- Calculate the area of :
- Determine the area of the parallelogram: Since is the height from to , and the area of parallelogram is twice the area of :
Thus, the area of the parallelogram is square units.
