Question

A rectangular yard measuring

Answer 1

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
