In parallelogram abcd, ab=18. identify ad.

cannot be determined

Step-by-step explanation:

In a parallelogram, the two opposite sides are equal. From the parallelogram ABCD given, it can be inferred that AB is parallel to CD and AD is parallel to BC i.e AB//CD and AD//BC.

Given AB = 18, side AD cannot be determined from the figure due to incomplete data given.

The data given can only be used to determine side CD since AB is equal to CD.

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

where is the figure
