Write an equation that describes each situation and solve.
1. A rectangular garden is fenced on all sides with 72 feet of fencing. The garden is 4 feet longer than it
is wide. Find the length and width of the garden.

180 square centimeters

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

1/4 because there is 4 grades.
