**Reiny**, Friday, January 25, 2013 at 12:19amgarden:

length = 10 ft

width = 9 ft

garden including walkway:

length = 10+2x

width = 9+2x

a) perimeter = 2(10+2x) + 2(9+2x)

= 20 + 4x + 18 + 4x

= 8x + 38

b) area of whole thing

= (10+2x)(9+2x)

= 90 + 38x + 4x^2

c) when x=4

area according to formula = 90 + 38(4) + 4(4^2) = 306

area using arithmetic:

length = 18

width = 17

area = 18x17=306
