# If sides A and B of a triangle have lengths of 5 and 6 respectively, and the angle between them is (pi)/2, then what is the area of the triangle?

$15 \text{sq.unit}$.

#### Explanation:

$\text{The angle btwn. sides A and B, i.e.,} \angle \left(A , B\right) = \frac{\pi}{2}$.

So, if we consider the side $B$ as Base, then side $A$ becomes

altitude on the base. Therefore,

The Area of the $\Delta = \frac{1}{2} \times \text{base"xx"altitude}$

$= \frac{1}{2} \cdot 5 \cdot 6 = 15 \text{sq.unit}$.
