Step-by-step explanation:
let the length of rectangle=l units
width=9
p=2(l+9)
area=9l

9l=2l+18
7l=18
l=18/7 units
Answer:
Player 1's position is Player 2's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.
Step-by-step explanation:
When you reflect a point (x, y) across the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign: it becomes (-x, y).
Thus, if a point P, say, (7,5) is reflected across the y-axis, its reflection P' becomes(-7,5)
It is 42. It is easy like the bottom one
