Given: $base = 18 cm$ , $height = 10 cm$

To find: Area of triangle

Solution:

\begin{array}{rcl} Area of Triangle & = & \frac{1}{2} \times base \times height \\ = & \frac{1}{2} \times 18 \times 10 \\ = & 9 \times 10 \\ = & 90 {cm}^{2} \end{array}

Therefore, the area of the given triangle is

90 {cm}^{2}
