the length of the rectangular area plus the road on each end is = 16 + (3*2) = 22 meters. the width of the rectangular area plus the road on each end is = 12 + (3*2) = 18 meters. the area of the rectangular area plus the width of the road is (22 * 18) = 396 square meters. the area of the rectangular area by itself is (16 * 12) = 192 square meters. the area of the road is the total area minus the rectangular area which is equal to (396 - 192) = 204 square meters. ans: 204 sq meters
