The coordinates of the vertices of the triangle are (–8, 8), (–8, –4), and . consider qr the base of the triangle. the measure of the base is b = 18 units, and the measure of the height is h = units. the area of triangle pqr is square units.

(10,-4)

12 units

108 square units

Step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
