What is A?
You solve this problem by moving everything to the right except for the A.
To do this, first add 40 to both sides of the equation.
A2 = 40
Second, Take the square root on both sides, this nullifies the square.
A = 400.5
(to the 0.5 power is the same as a square root)
Now you can solve this on a calculator.
A = 400.5 = 6.32455532
