Explanation of Solution

Given information: Base $b=15$ centimeters and height $h=12$ centimeters.

Formula used: Area of triangle $a=\frac{1}{2}\times base\times height$ where ‘b’ is the base and ‘h’ is the height.

Calculation: $a=\frac{1}{2}\times base\times height$

Putting the values.

  $=\frac{1}{2}\times 15\times 12$

Simplifying the expression.
