Hi Sierra,
 
Area of a square painting = 81p2 +90p +25
                                      = (9p+5)2 .......................................using formula, a2 +2ab +b2=(a+b)2
 
 
 
length of the painting = √area of a sq painting                                                           
                                = √(9p+5)2
                                = 9p + 5
