You have $25 to spend on picking 21 pounds of three different types of apples in an orchard. the empire apples cost $1.40 a
pound, the red delicious apples cost $1.10 per pound, and the golden delicious apples cost $1.30 per pound. you want to buy
twice as many red delicious apples as the other two types combined. how many pounds of each apple should you buy?

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

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
