the length and width of a rectangle are whole numbers of centimeters. neither is divide by 6.the area of the rectangle is 36 squ
1 answer:
Note that
- 36=1·36;
- 36=2·18;
- 36=3·12;
- 36=4·9;
- 36=6·6.
If neither (length and width) is divide by 6, then cases 1, 2, 3 and 5 are extra, because
- 36:6=6 (is divide by 6);
- 18:6=3 (is divide by 6);
- 12:6=2 (is divide by 6);
- 6:6=1 (is divide by 6).
The only possible dimensions are: width - 4 cm and length - 9 cm.
Then the perimeter is
cm.
Answer: 26 cm.

as the plane goes against the wind, the plane is not really flying at "x" mph, but is really going slower, at " x - y ", because the wind is subtracting speed from it.
likewise, when the plane is going with the wind, is not really going at "x" mph, but at " x + y ", is going faster due to the wind, thus
