a rectangular public garden x-ft. by y-ft. has a sidewalk surrounding the lawn.
the sidewalk is 6 ft. wide.
what are the dimensions of the lawn?
:
A surrounding walk 6' wide will subtract 12' from each lawn dimension, therefore
(x-12) by (y-12) is dimension of the lawn
:
what is the area of the lawn?
Area = (x-12)*(y-12)
FOIL
A = xy - 12x - 12y + 144, is the area
