2.)18x+10
Step-by-step explanation:

Y= 25
X=65
Because a triangle always has a total of 180 degrees.
Y and the 25 degrees are the same because I honestly forgot but trust. And the square means that the angle is 90 degrees so 90+25=115 and to get x you do 180-115=65.
I hope this was the right answer lol
-36 one of many possible answers.
Let the length of the playground be x, then the width is 6 + x.
Area = length * width = x * (6 + x) = 6x + x^2 = 216
Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18
i.e length = 12 and width = 6 + 18 = 18
