72 $\sqrt{3}$ units²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = ST = a = 12 and h = RS

To calculate RS use the tangent ratio in the right triangle and the exact value

tan60° = $\sqrt{3}$ , thus

tan60° = $\frac{opposite}{adjacent}$ = $\frac{RS}{ST}$ = $\frac{RS}{12}$ = $\sqrt{3}$ ( multiply both sides by 12 )

RS = 12 $\sqrt{3}$

Thus

A = $\frac{1}{2}$ × 12 × 12 $\sqrt{3}$ = 6 × 12 $\sqrt{3}$ = 72 $\sqrt{3}$ units²
