Verified answer

Answer:

l = (5a - 4) or (5a - 3)

b= (5a - 4) or (5a - 3)

Step-by-step explanation:

length × breadth = Area

l× b = 25a² -35a +12

lb = 25a² -20a -15a +12

lb = 5a(5a-4) -3(5a-4)

lb = (5a-4)(5a-3)

Required expression of length and breadth are:

• l = (5a - 4) or (5a - 3)
• b= (5a - 4) or (5a - 3)
