Question

the area of the triangle is 2/5 square foot the height is 6/5 ft. what is the length in feet of the base of the triangle?

Answer 1

`\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} A=(2)/(5)\\\\ h=(6)/(5) \end{cases}\implies \cfrac{2}{5}=\cfrac{1}{2}\left( b\cdot \cfrac{6}{5} \right)\implies \cfrac{2}{5}=\cfrac{6b}{10} \\\\\\ \cfrac{20}{5}=6b\implies \cfrac{20}{30}=b\implies \cfrac{2}{3}=b`
