Step-by-step explanation:

Step-by-step explanation:

We know that area=l*b

a^2+6a+8

= a^2+(4+2)a+8

=(a^2+4)+(2a+8)

=a(a+4)+2(a+4)

=(a+4)(a+2)

thus possible length and breadth cab be (a+4) and (a+2)

Or

Step-by-step explanation:

a²+6a+8

area of rectangle = l * b

factorise the given polynomial

sum is equal to 6

product is equal to 8

4+2=6

4*2=8

(x+2) (x+4)
