Richard walked around 2 rectangular parks. One measured 450 ft by 167 ft. The others measured 234 ft by 156ft. How far did he walk.?

To find the total distance Richard walked around the two parks, we first calculate the perimeter of each park. The perimeter of the first park (450 ft by 167 ft) is (2 \times (450 + 167) = 2 \times 617 = 1234) ft. The perimeter of the second park (234 ft by 156 ft) is (2 \times (234 + 156) = 2 \times 390 = 780) ft. Adding both perimeters together, Richard walked a total of (1234 + 780 = 2014) ft.
