Question 724378
The area of a rectangle is {{{ 6n^2+n-2 }}}. Which expression could represent the perimeter of of the rectangle?
6n^2+n-2
factor:
(3n+2)(2n-1)
These two factors could represent the length and width of the rectangle.
perimeter=2*length+2*width
=2(3n+2)+2(2n-1)
=6n+4+4n-2
=10n+2 (ans. D)
