Question

Give the possible expression for length and breadth of rectangle, if its area is given by 12a2 – 7a + 1.

Answer 1

Step-by-step explanation:

area of rectangle = length × breadth

12a^2 - 7a + 1 = L × B

12a^2 - 4a - 3a + 1 = L × B

4a (3a - 1) - 1 (3a - 1) = L × B

(3a - 1) (4a - 1) = L × B

so , length = (3a-1)

and breadth = (4a-1)
