You can put this solution on YOUR website!
F = 2A
F * A = 450
Substitute the known value of F from the first equation into the second
F * A = 450
(2A) * A = 450
Multiply
2a%5E2= 450
Divide each side by 2
a%5E2=225
Take the square root of each side
a = 15
If Angel is 15, then her father is twice that, or 30
15 * 30 = 450
