Ellis's backyard has a 6.256.256, point, 25 by 6.25\,\text{m}6.25m6, point, 25, start text, m, end text patio. she would like to build a 1.5\,\text{m}1.5m1, point, 5, start text, m, end text wide extension around 333 sides of the patio, as the figure shows. she will buy 0.250.250, point, 25 by 0.25\,\text{m}0.25m0, point, 25, start text, m, end text tiles that come 252525 to a package. how many packages does ellis need to buy to build the extension?

The answer is 21 I just did the quiz and 21 was the right answer.

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

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
