Step-by-step explanation:
hello :
the area is 4 7/20m × 6 2/3 m = ....... continu
the perimeter is : (4 7/20m + 6 2/3 m)×2 .........
56.8 feet per second = ? miles per hour
5280 feet = 1 mile
3600 sec = 1 hour
56.8/5280 = 0.01075 miles/second
(0.01075 miles/second)*(3600 seconds) = 38.72727 miles per hour
