Finding area of figure after transformation using determinant

WebJul 4, 2024 · The area of the triangle will be half of the determinant value. If the determinant is negative, then simply take the absolute value of it. A r e a = a b s o l u t e o f ( 1 2 x 1 y 1 1 x 2 y 2 1 x 3 y 3 1 ) Here we are assuming that this is 3x3 matrix, so the determinant function cannot find determinant of matrix which is not 3x3. Example Code WebUsing the determinant of a matrix we can find the area of a triangle whose coordinates are on the coordinate plane. Example: Black-necked stilts are birds that live throughout Florida and surrounding areas but breed mostly in the triangular region shown on the map. Estimate the area of this region. The coordinates given are measured in miles. thai food delivery pacific beach
