You find a parallelogram area by this formula:
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
And h is the perpendicular distance between both bases.

Answer:
The Figure for Right triangle is below,
Therefore , 15 unit length represents BC.
Step-by-step explanation:
Given:
Consider a right triangle ABC, Such that
To Find:
BC = ?
Solution:
In Right Angle Triangle ABC, Cosine and Tangent identity
BUT,
....Given
On Comparing,
Adjacent side to angle A = AB = 15
Opposite side to angle A = BC = 8
Hypotenuse = AC =17
Also Pythagoras theorem is Satisfies,
The Figure for Right triangle is below,
Therefore , 15 unit length represents BC.
