Step-by-step explanation:
hope I understand your qyestion
Equation 1 : R+G=20
Equation 2 : 7R+3G=9
Multiply Equation by 3, it becomes
3R+3G=60 ...... Equation 3
Now Equation 3 minus Equation 2
-4R = 51
R = - 51/4
Sub R into Equation 1, you can find G
Area of circle is about 50.30 inches squared.
Area of square box is 64 inches squared.
Lastly 64 inches minus 50.30 inches is 13.70.
So, 13.70 Square Inches Of The Box Is Empty.
