Answer:
factorize 35y² + 13y - 12
35y² + 13y - 12
35y² + 28y - 15y - 12
7y (5y + 4) - 3 (5y + 4)
(5y + 4) (7y - 3).
the lenght = 5y + 4
the breadth = 7y - 3

Answer:
l = (7y-3)
b= (5y+4)
Step-by-step explanation:
35y² + 13y -12
= 35y² - 15y + 28y -12
= 5y(7y-3) +4(7y-3)
= (7y-3)(5y+4)
Now u can consider them as length or breadth as u wish.
