Answer:
Step-by-step explanation:
The speed downriver was (16 mi)/(2 h) = 8 mph. The speed upriver was (16 mi)/(4 h) = 4 mph. The canoe's speed in still water is the average of these speeds: (8+4)/2 = 6 miles per hour.
The current's speed is the difference between the actual speed and the canoe's speed: 8 -6 = 2 miles per hour.
The speed of the canoe in still water is 6 mph; the rate of the current is 2 mph.
Perimiter is the distance around the shape. it is also the sum of the measures of the sides
so if you have a rectangle with sides legnth 4,4,2,2, then the perimiter is 4+4+2+2=12
area is dependent on the type of shape
basically, it is counting how much stuff in the shape
with a parallellogram, the area is legnth times width
so if you had a rectangle with legnth=4 and width=2 then the area is 4 times 2=8
I’m pretty sure it is 66 since the base would be congruent to the top so plug in 7 into 10u-4 and u get 66!! (You plug in 7 since u=7)
