Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Identify the base and height

From the diagram, the base of the triangle is $1$ mm and the height is $\frac{1}{2}$ mm.

Step3: Substitute the values into the formula

Substitute $base = 1$ and $height = \frac{1}{2}$ into the formula: $A=\frac{1}{2}\times1\times\frac{1}{2}$.

Step4: Calculate the area

First, multiply $1$ and $\frac{1}{2}$ to get $\frac{1}{2}$, then multiply by $\frac{1}{2}$: $\frac{1}{2}\times\frac{1}{2}=\frac{1}{4}$.

Answer:

$\frac{1}{4}$
