Answer

$\text{*320 cm}^2*$

Step 1: Identify the formula for the area of a triangle. The area of a triangle is given by the formula: $A = \frac{1}{2} \times base \times \text{height}$

Step 2: Substitute the given values into the formula. The base is $20 \text{ cm}$ and the height is $32 \text{ cm}$ . $A = \frac{1}{2} \times 20 cm \times 32 \text{ cm}$

Step 3: Calculate the area. $A = 10 cm \times 32 \text{ cm}$ $A = 320 cm^2$

The area of the road sign is $\boxed{*320 cm^2*}$ .
