A) \( \Large 6cm^{2} \) |

B) \( \Large 8cm^{2} \) |

C) \( \Large 10cm^{2} \) |

D) \( \Large 12cm^{2} \) |

Correct Answer:

A) \( \Large 6cm^{2} \) |

Description for Correct answer:

Since, the triangle is right angled.

All the three consecutive sides must satisfy Pythagoras theorem 3, 4 and 5 are the sides of triangle which satisfy Pythagoras theorem.

\( \Large (5^{2}=4^{2}+3^{2}) \)

Area of triangle = \( \Large \frac{1}{2}\times 4\times 3=6cm^{2} \)
