<h3>question:-</h3>
find the area of the triangle with vertices(1,2),(2,3),and(4,5).
-5 and 21
21 - 5 = 16
21 × (-5) = -105
is the determinant of the coefficient matrix:

is the determinant of the coefficient matrix, but this time you replace the
-coefficients with the values on the right hand side of the equations:

Answer:
32
Step-by-step explanation:
Side AD = 4
9-5=4
Side DC = 13
a^2+b^2=c^2
5^2+12^2=c^2
25+144=c^2
169=c^2
13=c
Side AC = 15
a^2+b^2=c^2
9^2+12^2=c^2
81+144=c^2
225=c^2
15=c
