A triangular college pennant flag has a baes of 12 inches and a height of 30 inches how many square inches of wall space will you need to hang up six pennants?

Step-by-step explanation:

-The cumulative area of the six is equivalent to the sum of their individual areas.

-Area of a triangle is given by:

We substitute  given values in the equation and multiply by the number of pennants:

Hence, the total area needed is

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

21/58.
