Asap need the answer! the map of a walking trail is drawn on a coordinate grid with three points of interest. the trail starts at r(−1, 4) and goes to s(5, 4) and continues to t(5, −2). the total length of the walking trail is units. (input whole numbers only.) numerical answers expected! answer for blank 1:

Heyyy, is this an iready question?

The answer is 12

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
