Answer:
4 meters
Step-by-step explanation:
Normally, 100 centimeters should be the normal meter length, but we multiply that by 4 and we get 400 centimeters
The water weighs 0.29 kg.
Subtract the weight of the filled water pitcher by the weight of the empty water pitcher to find the weight of the water.
2.01 - 1.72 = 0.29
Exact perimeters given coordinates are ugly, the sum of a bunch of square roots. A calculator approximation isn't so bad, especially when the choices are so far apart; we can just keep one decimal place.
There's only one rule in play, that the length of a segment with endpoints (a,b) and (c,d) is given by the Pythagorean Theorem as
It's going to be too boring for me to do more than one or two, so hopefully you'll learn how and do the rest yourself.
E(2,9),F(2,2),G(10,2)
Of course there's a shortcut when one of the coordinates between the endpoints is the same; then we can just skip the square root.
So an approximate perimeter of 7+8+10.6=25.6
First choice
One more, a quadrilateral
M(1,8), N(9,8), O(9,2), P(1,2)
No square roots needed for that one, which is apparently a rectangle, perimeter 8+6+8+6=28
Second choice
I leave the rest for you
