53 = (10 x 5) + 3

7 x 53 = (7 x 5 x 10) + (7 x 3)

7 x 5 x 10 = 35 x 10 = 350
7 x 3 = 21

350 + 21 = 371

The length is 19.5 feet. this is because when you add the yards, it equals 15 feet. Next, add 1 + 2 feet from the first and second jump. 10+8 inches equal 1.5 feet. Next, add 15 feet+3 feet+1.5 feet to get 19.5 feet.
