WebImagine a triangle with vertices at (x 1,y 1), (x 2,y 2), and (x 3,y 3).If the triangle was a right-angled triangle, it would be pretty easy to compute the area of a triangle by finding one-half the product of the base and the height (area of triangle formula). However, when the triangle is not a right-angled triangle there are multiple different ways to do so. WebApr 6, 2024 · determinant, in linear and multilinear algebra, a value, denoted det A, associated with a square matrix A of n rows and n columns. Designating any element of the matrix by the symbol arc (the subscript r identifies the row and c the column), the determinant is evaluated by finding the sum of n! terms, each of which is the product of … WebTaking the horizontal side as the base, we get that the length of the base is 4 and the height of the triangle is 9.
