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
= 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
