area of a triangle

area = (base*height on the base) /2

          =(1*1.4)/2

area= 0.7 square centimeters

\(\color {magenta}\frac{1\times1.4}{2}\color{black}=\color{cyan}1\times0.7\color{black}=\color{magenta}\textbf{0.7}cm^2\)

\(\color{blue}\textbf{I am using} \color{blue }\LaTeX\)

I am so happy about knowing I can use colors in LaTeX so I am too happy to show off XD
