Problem: How to find the area of the triangle formed by the points (1, 3),(3, -1),(-5, -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_vcMWwLqPgKnru18AeWOWmRgziAy0mGWCbrOYM4J3ucIhKoRgxkPTyLXN0wT9fL8uyg0XlA3k70fUnooyAzrGay93psA7Y3DdFe-ebAGif_ID41guEmxx4SVXfIgtNqWxjKm2Pb2ACI7kzdaX9Mf8V95TQ6jzmECb9mjgTX0g=s0-d)
Applying the formula,we get
![\frac{1}{2}|[1(-1+5)+3(-5-3)-5(3+1)]|\,](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_uEjWrZCwycrNtDbP0pdJjSQExz3OdEo4XqkugMt6PNDjSZ31ZLUUaIEB2IPgfPyE9Kk78fB_pw9XsutkWY4AqSwHb1W_RntcHp0px9kqBpZOUbbBrKZdPBiUDcLiV6C0oH4n2GSaQhwkRwGWm-ZL9GvB4bS6CqZbIsQ9MBAw=s0-d)
Therefore, the area of the triangle is 20.
