Mike wants to paint one wall of his room. the wall measures 12 feet by 9 feet. on the wall is one square window the measures 4 1/2 feet on each side. which of the following best decribes the number of square feet mike will paint?
a.87 3/4 square feet
b.103 1/2 square feet
c.99 square feet
d. not here

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get 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
