Answer:

3,200 centimeters

Step-by-step explanation:

12 meters represent 1,200 centimeters.

Therefore, the perimeter in centimeters is : 2*1,200+2*400=2,400+800=3,200 centimeters.

A fisherman can row upstream at 5mph and downstream at 10mph he started rowing upstream until he got tired and then rowed downst
AlekseyPX

We have been given that the upstream speed is 5 mph and the down stream speed is 10mph.

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is s = \frac{d}{t}

Hence, t= \frac{d}{s}

Time upstream +  time downstream = 6

\frac{x}{5} +\frac{x}{10} =6

lcm = 10

\frac{2x+x}{10} =6

=> \frac{3x}{10} =6

Cross multiplying, 3x= 60

x = 20 miles .. Answer.
