How to find the area of the triangle formed by the points (5, 2),(-9, -3),(-3, -5).
Solutions:
The formula for finding the area of the triangle formed by
![\frac{1}{2}|[x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)]|\,](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_so2wEQfUL4UEVux6M8ZsqndaEJuaTZBYDpeiHG95DIVOcJmvuJLLMUCFl-eOOx_ca8h0XfETovzG3NSN0ehMuOGT6zx9RygAKsfrhdQSInWWwb7b290veeLx1JH6WoQt8ocHcW4VxSniYYguOs26d-lcnceEckqtw9Ozp4Cg=s0-d)
Applying the formula,we get
![\frac{1}{2}|[5(-3+5)-9(-5-2)-3(2+3)]|\,](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_tpctHNJ3Wfbsk1eFlo77ZYcSfMlRuL2bSMqgd1v9lZc72aFDPXv_pWERxPQ4wOwf1V1wCI6B0Rf42FcX_o_ay7QStJyjW904Q7wkKbYv0OezMugvFmWf8-fBkYmoQuz36VeKBzzveP-QwAZfQ1KCwVmBSf8zSMvEqXrvBtgA=s0-d)
Therefore, the area of the triangle is 29.
