Explanation:

Step1: Recall area formula

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

Step2: Identify base and height

Here, the base is 5 cm and the height is 15.4 cm.

Step3: Calculate area

$A = \frac{1}{2}\times5\times15.4= 38.5$ $cm^{2}$

Answer:

$38.5$ $cm^{2}$
