Answer 1

Answer:

Step-by-step explanation:

Q. The following expression is the area of the rectangle. Find the possible length and breadth of the rectangle.

x² + 19x -20

=  x² + 20x - x -20

= x ( x + 20 ) -1 ( x + 20 )

= ( x+20 )( x-1 )

hence the possible length and breadth are  ( x+20 )cm and ( x-1 )cm
