The possible dimensions of the painting are ( x - 9 ) and ( x + 4 ).
What is a rectangle?
'A rectangle is a special case of a parallelogram in which each pair of adjacent sides is perpendicular.'
According to the given problem,
The given area = x² - 5x - 36
⇒ x² - 9x + 4x - 36
⇒ x( x - 9 ) + 4( x - 9 )
⇒ ( x - 9 )( x + 4 )
Hence, we can conclude, the possible dimensions of the rectangular painting is ( x - 9 ) and ( x + 4 )
