The area of a triangle is represented by the following expression:

[tex]\begin{gathered} A=\frac{b\cdot h}{2} \\ \text{where,} \\ b=\text{base} \\ h=\text{height} \end{gathered}[/tex]

With the information given, we know that base is 21cm and height is 23cm, now we can substitute and calculate the area:

[tex]\begin{gathered} A=\frac{21\cdot23}{2} \\ A=\frac{483}{2} \\ A=241.5cm^2 \end{gathered}[/tex]
