Question 268748
The area of Beth's rectangular garden is(x2+13x+42)ft.2.the with is(x+6)ft.
what is the length of the garden?

Area = length*width so

length = area/width

So in this case:

length = (x^2+13x+42)/(x+6) or

length = [(x+6)*(x+7)]/(x+6)

length = x+7

The perimeter P of a rectangle is 2*length + 2*width

In this case:

P = 2*(x+7) + 2*(x+6)
