Answer:
Perimeter: 28 Meters
Area: 33 Square Meters
Step-by-step explanation:
To calculate the perimeter:
<u>Formula:</u> P = (L + W) × 2
P = (3 + 11) × 2
P = 28 Meters
To calculate the area:
<u>Formula:</u> A = LW
A = 11 × 3
A = 33 Square Meters
It will be D by multiplying the numerator and the denominator by the unit rate of 6
Answer:
Tally marks
Step-by-step explanation:
It is most likely tally marks because all of the other options are more recent than option b the Greek and Latin letters are dated to be closer to the modern times than the cavemen were.
Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
