The image below is a scale drawing of a parking lot. The length of each square on the grid represents 0.5 cm. The actual parking lot has a perimeter of 84 m. Draw another scale drawing of the building using the scale 2 m to 1 cm length from the building to the drawing. Explain your reasoning.

4 + 5 7/9= 9 7/9

step-by-step explanation:

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
