Find the area of `DeltaABC`, if a=6m and `angleB`and `angleC` are respectively `30^(@)` and `90^(@)`.

Explanation

To find the area of triangle ABC where side \( a = 6 \) m, \( \angle B = 30^\circ \), and \( \angle C = 90^\circ \), we can follow these steps:

### Step 1: Identify the triangle type
Since \( \angle C = 90^\circ \), triangle ABC is a right-angled triangle with \( C \) as the right angle.

### Step 2: Use the properties of the triangle
In a right triangle, we can use the definitions of trigonometric functions to find the lengths of the other sides. We know:
- Side \( a \) is opposite to angle \( A \).
