You can think of a square as two isosceles right angle triangles and use Pythagoras.
x^2 + x^2 = 22^2
x^2 + x^2 = 484
2x^2 = 484
x^2 = 242
x = 11√2
One side of the playground is 11√2 m long.

Answer:
x = -45
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides:
(x/5) * 5 = (-9) * 5
x = -9 * 5
x = -45
x = -45 is your answer.

Answer: 9= -1.5 or -3/2
10= -11/6 or 1.8333
11= -10.9
12= 3.535
13= Town A is -3.33 Town B is -3 2/5, 2/5= .44, so town B is colder, as it is -3.44
14= I'm not sure about number 14, sorry about that
