Question

The area of rectangle is a^2+6a+8sq.units,Find it's length and breadth .Also find the perimeter of the rectangle. ​

Answer 1

Answer:

a^2+6a+8

=a^2+4a+2a+8

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

=(a+4)(a+2)

so,length if the rectangle is (a+4) unit

breadth of the rectangle is (a+2) unit

and perimeter of the rectangle is

2(length+breadth)

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

=2(2a+6) unit

=4(a+3) unit
