Answer:

Step-by-step explanation:
Step 1: Simplify square roots
√72 = 6√2
√50 = 5√2
So, 
Step 2: Cancel like terms

Step 3: Rewrite
And we should get our answer!
132 is rounded to the 130 cause you just look at the last number and you see what is the closes zero that's why it is 130
Total area = 12 x 24.6 = 295.2
Area of circle = 3.14 x 3.6² = 40.69
Area of square = 4.2 x 4.2 = 17.64
Square and circle = 40.69 + 17.64 = 58.33
Probability = 58.33/295.2 = 0.1976
Rounded answer = 0.20
