Given: $base = 20 cm$ , $height = 11 cm$

To find: Area of triangle

Solution:

\begin{array}{rcl} Area of Triangle & = & \frac{1}{2} \times base \times height \\ = & \frac{1}{2} \times 20 \times 11 \\ = & 10 \times 11 \\ = & 110 {cm}^{2} \end{array}

Therefore, the area of the given triangle is

110 {cm}^{2}
