18 cm | |

14 cm | |

12 cm | |

8 cm |

Question 1 Explanation:

$ \begin{array}{l}\frac{1}{2}altitude\times 9=36\\=>altitude=8\end{array}$

Question 2 |

What is the area of an equilateral triangle having altitude equal to 2√3 cm?

√3 sq cm | |

2√3 sq cm | |

3√3 sq cm | |

4√3 sq cm |

Question 2 Explanation:

$ \begin{array}{l}Let\text{ }the\text{ }side\text{ }of\text{ }the\text{ }triangle\text{ }=\text{ }x\text{ c}m\\\frac{\sqrt{3}}{4}{{x}^{2}}=\frac{1}{2}\times 2\sqrt{3}x\\=>x=4.\\Area=4\sqrt{3}sq.cm.\end{array}$
