Answer :
To begin with, we will sketch the triangle
The area of a triangle is obtained using the formula
[tex]\text{Area}=\frac{1}{2}\times base\times height[/tex]Thus, the area is
[tex]\begin{gathered} \text{Area}=\frac{1}{2}\times7\times8 \\ \\ \text{Area}=7\times4 \\ \\ \text{Area of the triangle is 28cm}^2 \end{gathered}[/tex]
