What method can you use to find the area of the composite figure? Check all that apply.
decompose the figure into one rectangle and one triangle, and add the areas
decompose the figure into two trapezoids, and add the areas
find the area of the larger rectangle, then subtract the area of the square
find the area of the larger rectangle, then subtract the area of the two small triangles
find the area of the larger rectangle

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

d 600 because 15*10*2=300

300+300=600
