A training held is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 84 m long and 59 m wide. What is the length of a training track running around the field? (Use the value 3.14 for , and do not round your answer. Be sure
to include the correct unit in your answer.)

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
