Consider this rectangle. The perimeter is P = 2(3) + 2(6) = 18 cm. Suppose the dimensions of the rectangle are all multiplied by 4. The new rectangle would have the dimensions The perimeter of the new rectangle would be 6 cm cm. The new perimeter will be times as large a the perimeter of the original rectangle. 3 cm ​

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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
