Answer:
option B is correct
Step-by-step explanation:
Area: 16x2 + a + 12
= 25a2 – 20a – 15a + 12
= 5a(5a – 4) – 3(5a – 4)
= (5a -4) (5a – 3) length × breadth
= Area of rectangle (5a – 4) (5a – 3)
= 25a2 – 35a + 12
∴ Length = (5a – 4)
Breadth = (5a – 3)
(ii) Area : 35y2 + 13y – 12
Area of Rectangle – Length × Breadth 35y2 + 13y – 12
35y2 + 28y – 15y
7y(5y + 4) – 3(5y + 4)
(7y – 3) (5y + 4)
∴ Length = (7y – 3)
Breadth = (5y + 4)
