The height of a triangle represented by a line segment, is the perpendicular distance from a vertex to the line containing a base. Determine the area of triangle ABC

The area of triangle ABC = 18 square units
Explanation:The height of the triangle, h = 9
The base of the triangle, b = 4
The area(A) of the triangle is given by the formula:
[tex]\begin{gathered} \text{Area = }\frac{1}{2}\times base\times height \\ A\text{ = }\frac{1}{2}bh \end{gathered}[/tex]Substitute b = 4 and h = 9 into the formula:
[tex]\begin{gathered} A\text{ = }\frac{1}{2}\times4\times9 \\ A\text{ = 18} \end{gathered}[/tex]The area of triangle ABC = 18 square units
