A rectangular yard measuring

36ft

by

54ft

is bordered (and surrounded) by a fence. Inside, a walk that is

3ft

wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.

The entire yard is 36x54 so you would draw a rectangle with those measurements, since there is a border of 3 you should draw another rectangle in the middle with measurements 6 less than the original. 30x48

since you are finding the area of the walk, you would find the larger area, then subtract the smaller rectangle

(36*54) - (30*48)

1944-1440

504 square feet of walk
