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_uI-CUZLMWmLRw0uEFZThHoxEFOGAtUASrF35emLDKWCeoSHtJ1MHOfHnS9w8isxctiun0kvGwclH0I1HHbd_U_URlMqKS1OpTGNbj5TIH2nkyga8DOSVqgnJONCqwAAcqIUKs-vQI-JBvOCmadIAVU3XuEPbqvM7Y4tg5Mqw=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_vXD1xLG3veemVXJ7YQlwr5wVz-MBj3wmwBfLBVZU9U8LVXPhGnxJ48MOpaJB9B-IHmu88xTxUEPbqKtvUVwZBKPStNoWbgoaulBw8WAnMw-BBfDvlwqSSUJwRnvYPU1rq2vL6Quw6kSw8zt-Oetx00N-l8FSyfZ7hpACczZA=s0-d)
Therefore, the area of the triangle is 29.
